the chinese lands near heilongjiang are the 64 villages east of the river. the Russians are the biggest robbers of the Far East, unscrupulous stealing lands from the Chinese, Japanese and Korean from the past. but the world have forgotten or conveniently ignored what the Russians did.
regarding the Tibetan who were perceived as peace-loving people who suffered at the hands of the Chinese. the fact was the Tibetan government was embroiled in the politics of Republican China from 1911-1949. the Tibetan regularly instigated the minorities to rebel against the Chinese authorities in Qinghai and Xikang. the Tibetan army also fought some battles against warlord Ma Bufang to grab adjacent lands near Tibet. Chinese Communist agents who were pursued to desperation by the Kuomintang secret police would find a safe haven in the Tibetan borders, protected by the Tibetan authorities. those agents would laid low for a while, waiting for another opportunity to re-enter the China borders. the Communist who hid under the protection of the British in Shanghai would go to Hongkong or Tibet and then re-enter China again.
the Tibetan really deserve to be screwed by the PRC. retribution.
