893.01 Manchuria/879: Telegram
The Ambassador in Japan (Grew) to the Secretary of State
[Received April 18—2 a.m.]
81. Reports which have reached the Embassy from various sources indicate that Japanese or so-called Manchukuo agents are endeavoring to induce Mongolian princes in Chahar to give allegiance to [Page 279] Manchukuo. If a sufficient proportion of the Province of Chahar can be brought under the Manchukuo flag in this way we may reasonably expect Chahar to be claimed as a part of Manchukuo territory and the Province to be brought under the influence of the Japanese Army. The latest reports indicate that Manchukuo is about to obtain the allegiance of the Silingol Mongols living along the Kalgan-Urga caravan route, thus closing the route to Chinese trade.
