### FAQ

#### Is a PMP certification worth it?

A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations.

#### What are the best certifications for project managers?

The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation.

#### How does PMI support career growth for professionals?

PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers.

#### What is the PMBOK® Guide?

The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery.

#### How is AI changing project management?

AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment.  PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes.

#### What are the most important skills for a project manager?

Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates.


#### How can I get involved with the PMI community?

Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions. Online, PMI's projectmanagement.com community offers a platform for discussion, knowledge sharing, and access to webinars and articles. Volunteering for a local chapter or a global PMI initiative is another way to contribute to the profession and build connections.

#### What is the difference between PMP and CAPM?

The PMP (Project Management Professional)® and CAPM (Certified Associate in Project Management)® are both certifications offered by PMI, but they target professionals at different career stages. The CAPM is an entry-level certification designed for individuals with little or no project experience, validating their understanding of fundamental project management knowledge and terminology. The PMP is for experienced project managers and requires a combination of formal education and years of documented project leadership experience, making it a more advanced and globally recognized certification.

#### How does PMI support social impact?
PMI supports social impact by helping individuals, nonprofits, NGOs, and communities use project management to turn purpose into measurable outcomes. Through the PMI Educational Foundation, PMI expands access to project management education for youth worldwide, including underserved and underrepresented populations. Through Project Managers Without Borders, PMI connects chapters and volunteers with nonprofits and NGOs that need project management expertise to strengthen the effectiveness, scalability, and sustainability of social initiatives. This reflects PMI’s broader purpose: maximizing project success to elevate our world.

Both Cambodia and Thailand have been [rated](https://www.phnompenhpost.com/business/cambodia-voted-worlds-friendliest-country-rough-guides-reader-poll) among the friendliest nations in the world, and just five years ago, the Southeast Asian neighbors thought their friendship with each other could never be broken. “As we share a long border, we both know that we have to live and grow together,” Thailand’s then-Ambassador to Cambodia Panyarak Poolthup [told](https://www.phnompenhpost.com/national/thailand-cambodia-two-kingdoms-friendship-standing-test-time) Cambodia’s then-Prime Minister Hun Sen. “The political will is always there to resolve any issues that may arise.”

But in recent weeks, bilateral relations have sunk to a dangerous new low, threatening to reignite a historic rivalry that had seemed to be a relic of the past.

Following weeks of standoff, including Cambodia invoking the language of “war,” since a Cambodian soldier was killed in a clash along the border last month, Thai Prime Minister Paetongtarn Shinawatra issued her strongest rebuke yet, signaling resolution likely remains distant.

“Thailand is united. We will not tolerate maltreatment, accusations or threats from any party. Our country also has dignity. Our country is also strong,” Paetongtarn [said](https://www.bangkokpost.com/thailand/general/3050711/strident-pm-declares-thailand-will-defend-its-sovereignty), in response to Cambodia retaliating with cross-border embargoes and taking the dispute to the International Court of Justice, which Thailand does [not recognize](https://www.nationthailand.com/blogs/news/asean/40051314) the jurisdiction of.

Here’s what to know about the conflict—and its potential consequences.

## What has happened in recent weeks?

The reescalation of conflict was sparked on May 28, when a Cambodian soldier was killed in an early morning clash between both nations’ troops, in an area called the Emerald Triangle—the shared border between Thailand, Cambodia, and Laos. The area remains disputed as both Thailand and Cambodia lay claims to parts of the region.

Both sides argued that the other was the aggressor: Cambodia’s Ministry of National Defense [said](https://mod.gov.kh/contents/uploads/2025/05/IMG%5F20250528%5F0001.pdf) the Thai army opened fire on a trench that had been a Cambodian army base, leading to the death of the soldier, while Thailand’s army [claimed](https://www.bangkokpost.com/thailand/general/3036327/thai-cambodian-soldiers-in-brief-clash-no-casualties) that its soldiers responded only after the Cambodian forces “started using weapons” during a misunderstanding in the disputed area.

Hun Sen, who relinquished the Cambodian premiership to his son in 2023 but became the Senate President and remains the effective country leader, [reacted](https://www.facebook.com/hunsencambodia/posts/1321171426031308?ref=embed%5Fpost) to the skirmish, saying that he supports the “decision to send troops and heavy weapons to the border to prepare for a counterattack in case of a further invasion.”

“We hate war, but we are compelled to wage it when facing foreign aggression,” Hun Sen said. 

As members of the regional bloc Association of Southeast Asian Nations, Cambodia and Thailand are expected to resolve disputes peacefully, per the [ASEAN charter](https://asean.org/wp-content/uploads/images/archive/publications/ASEAN-Charter.pdf). While both countries [initially beefed up](https://www.aljazeera.com/news/2025/6/7/thailand-and-cambodia-reinforce-troops-along-disputed-border-thai-minister) military presence on their respective sides of the border, on June 8, they appeared to attempt a deescalation by sending their troops back to military positions that were agreed upon last year. Paetongtarn, in a [statement,](https://x.com/ingshin/status/1931685763273605120) said the countries agreed “to jointly adjust military forces at points of conflict to reduce the atmosphere of confrontation.”


But the dispute escalated through punitive tit-for-tat policies seemingly designed to appease fomenting nationalistic sentiment on their respective sides of the border.

The Thai army [took control](https://www.bangkokpost.com/thailand/general/3044047/thai-army-takes-control-of-border-checkpoints) of border checkpoints and Bangkok [threatened](https://www.nationthailand.com/news/asean/40051025) to cut electricity and the internet to Cambodia. Cambodia [responded](https://apnews.com/article/border-internet-tv-movie-ban-1d554bda4b59aa89b79f02ad2913acc7) by banning Thai media like TV and movies, and disconnecting cross-border internet links to Thailand.

Thailand, meanwhile, [barred](https://www.bangkokpost.com/thailand/general/3051507/army-prohibits-thais-crossing-border-to-work-in-poipet-bars-casinos) Thais from crossing the border to work in casinos and other entertainment venues in Cambodia’s Poipet. 

Further inflaming tensions, Cambodian Prime Minister Hun Manet announced on Facebook on [June 16](https://www.facebook.com/permalink.php?story%5Ffbid=pfbid026SS4TiFZtKibtNmYqZVooHPDBU6nzzdSrjE9omBTjGoXZTyqmNGWKZj3DZLNWHEkl&id=100069511484329&%5F%5Fcft%5F%5F[0]=AZWvdc4SnFJC9ooA8PqkAcYKSSvjMZU99szxLKfB5UlqIVeOg7NyS-9CpyXbDM-zU0X-YvO2U3wS%5FZsR1rcsqISDhrIBJuRnJL2vlPyU%5Fv7WbelOI7ENQlQmWY7GboZIun2GWrnbUw2XU1bxRfC-6B7X5ldaweHMxG03ozp5kHehqea7r63XdXYULOPq5q6YrQxO-iEunOg0fmU6IUywp-Za&%5F%5Ftn%5F%5F=%2CO%2CP-R) that Cambodia sent an official letter to the International Court of Justice to help find a solution to the border development issues. “Cambodia chooses international law and peace,” he said the [day before](https://www.facebook.com/permalink.php?story%5Ffbid=pfbid0K3AAGz5m3BSJhbtYW7CQ4vak3L63GzPmQsKEvENzChD4HoRAvrFz7PeDFisuyuvkl&id=100069511484329&%5F%5Fcft%5F%5F[0]=AZWAlvkGWwDvwZKKMid4dcJLGsyBv0u5Sj4-xTTdpfaQvIx7MOBNniUWeThVLSyS5%5F%5FXB71NvOWpXPVx8p3QmnETi72L0diGS2PYvn90DlfwxQBhEecyxTYmL0iFPu4dmEVd3MIBX-mTlXDECAtzNzbBtqimo4b8oW1g1hfVISlpQ4NW0-e2WwYuCTvUCItEecaKPusk%5FmZSbFVsTM9iUZwP&%5F%5Ftn%5F%5F=%2CO%2CP-R). 


Thailand’s foreign ministry has [ruled out](https://www.mfa.go.th/en/content/thai-position-response-to-cambodia-icj-en?cate=5d5bcb4e15e39c306000683c) an intervention from the ICJ and made clear its preference for bilateral talks, arguing that “a third party may not always be conducive to the preservation of amicable relations among States, particularly in sensitive matters involving complex historical, territorial, or political dimensions.” 

## What is the historic context?

Cambodia and Thailand share an 817-km. land border, but that border was largely mapped by French colonizers while they occupied Cambodia from 1863 to 1953\. A 1907 map was based on an agreement to follow a natural watershed line between Thailand and Cambodia. But Thailand later contested the map over the fact that it placed the 11th-century Preah Vihear Temple in the Dângrêk Mountains within Cambodian territory.

The dispute, as well as [historical differences](https://www.nationthailand.com/news/asean/40051324) in cartographic methods, led to areas around the border that both countries lay claim to.


There have been attempts to clarify demarcations. Cambodia brought Thailand to the International Court of Justice in 1959 over the temple dispute, and in 1962 the court [ruled](https://www.icj-cij.org/sites/default/files/case-related/45/4873.pdf) in Phnom Penh’s favor, saying that Preah Vihear falls in Cambodian territory. Thailand recognized this at the time but argued that the surrounding frontiers were still disputed, which further complicated the borderlines.

Tensions flared in 2008 when Cambodia sought a UNESCO world-heritage status for the Preah Vihear Temple. After the temple received the recognition in July, military clashes between Cambodian and Thai troops [erupted](https://time.com/archive/6944665/thai-cambodian-border-spat-heats-up/) near the border area.

These clashes lasted for years, coming to a head in [2011](https://time.com/archive/6957211/deadly-clashes-as-thai-cambodian-temple-tensions-reignite/), after displacing 36,000 at the height of the conflict in [April that year](https://reliefweb.int/report/cambodia/cambodia-thailand-36000-displaced-deadly-border-clashes). Around this time, Cambodia took to the ICJ again to interpret its earlier 1962 ruling, and the court affirmed its previous decision two years later.


Thailand has pushed for a more bilateral approach, with a Joint Boundary Commission (JBC) established in 2000 to help resolve border disputes. Cambodia has engaged with Thailand through the JBC, but these meetings—the latest of which was scheduled on June 14 in Phnom Penh—tend to produce [no significant results](https://www.bangkokpost.com/thailand/general/3050052/no-conclusions-from-thai-cambodian-joint-boundary-meeting). 

## What could come next?

Resolving the border dispute quickly seems unlikely.

Complicating matters is the relationship between the two countries’ current leaders—and their fathers. Paetongtarn’s father former Thai Prime Minister Thaksin Shinawatra and Cambodian Prime Minister Hun Manet’s father Hun Sen have a public friendship, with Hun Sen even providing refuge to Thaksin in Cambodia and naming him as an [honorary economic adviser](https://time.com/archive/6948517/latest-pawn-in-the-thai-cambodian-spat-thaksin/) after Thaksin was ousted in a coup in 2006.

The relationship between the two has caused concern about how the border dispute will be resolved, particularly for Thailand. 


When Paetongtarn was asked about whether she’s becoming “too soft” on Cambodia because of the relationship, she [responded](https://www.khaosodenglish.com/politics/2025/06/05/thailand-cambodia-border-tensions-rise-with-nationalism/): “Even though our two families are friends, it doesn’t mean we would allow the country to lose its interests … if a friend asks for your house, no friend would just give it away.” 

Paetongtarn’s comments come as the Royal Thai Army said it was ready for a “[high-level operation](https://www.reuters.com/world/asia-pacific/thai-military-prepared-high-level-operation-if-cambodia-border-row-escalates-2025-06-06/)” if necessary to address the situation at the border. Paetongtarn has reiterated calls for a peaceful resolution to the dispute, but being at odds with the Army has echoes of previous government downfalls: both her father Thaksin and aunt Yingluck Shinawatra, another former Prime Minister, were ousted following nationalists groups’ revival of border issues.

In an analysis for Asian current affairs magazine [_The Diplomat_](https://thediplomat.com/2025/06/is-thailand-on-the-cusp-of-another-military-coup/), Royal University of Phnom Penh’s Center for Southeast Asian Studies researcher Rath Pichanvorlak warned that the Thai military “could allow border tensions to escalate, inflaming nationalist sentiment,” to justify another coup.
