Following the Chinese Communist Revolution at home, China established their embassy to Vietnam on a hill in Đại Từ district, Thái Nguyên province, since Hanoi was unavailable at the time due to the First Indochina War.
It was here that China's first ambassador to Vietnam, Luo Guibo, submitted his credentials to Ho Chi Minh.
[1] On August 25, 1954, after Vietnamese victory in the war, China decided to establish an embassy in Hanoi proper.
Ho Chi Minh allowed the Chinese delegation to freely choose a location anywhere in Hanoi and report back to him.
The current site of the Chinese Embassy was originally the official residence of Hoàng Trọng Phu, a former minister of French Tonkin.
