Troubles of the past few weeks were supposed to be caused by a border dispute, but since the district between the Manchukuan province of Hsingan and Outer Mongolia has never been accurately surveyed, even Japanese maps never put the border in exactly the same place in any two editions. In some embarrassment the Chief of the Mongol Affairs Department of the Manchukuan Government, left Hailar last week for the great and little known lake of Bor Nor. With him he took a whole battalion of surveyors to establish 28 observation posts along the border, rectify the present “typographical errors” that show the Mongol border passing sometimes through the lake, sometimes around it. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/archive/6753787/manchukuo-border-at-bor-nor/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/archive/6753787/manchukuo-border-at-bor-nor/"},"headline":"MANCHUKUO: Border At Bor Nor","datePublished":"1935-02-25T05:00:00.000Z","dateModified":"2026-02-28T15:25:17.793Z","description":"Manchukuan and Mongolian border guards were still sniping at each other ineffectively last week (TIME, Feb. n & 18) when precise Japanese army headquarters at Mukden suddenly realized that...","url":"https://time.com/archive/6753787/manchukuo-border-at-bor-nor/","keywords":[],"thumbnailUrl":"","author":[{"@type":"Person","name":"TIME","url":"https://time.com/author/time/"}],"articleSection":"U.S.","image":[],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/us/","name":"U.S."}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/archive/6753787/manchukuo-border-at-bor-nor/","name":"MANCHUKUO: Border At Bor Nor"}}]}] ```
