| Ambassador/Kazakhstan |
Most diplomatic relations between Kazakhstan and other countries were established during 1992. Some were slightly earlier. The United States and the Republic of Kazakhstan established diplomatic relations on December 16, 1991. After the Kazakh oil boom from the late 1990s onward, the diplomatic presence in the republic increased.
Diplomatic relations between Russia and Kazakhstan have fluctuated since the fall of the Soviet Union but both nations remain particularly strong partners in regional affairs and major supporters of the Collective Security Treaty Organization, the Shanghai Cooperation Organisation and Eurasian Economic Union. Kazakhstani-Russian relations have been strained at times by Kazakhstan's military and economic cooperation with the United States as well as negotiations over Russia's continued use of the Baikonur Cosmodrome, however the two nations retain high-level military and economic cooperation perhaps second among former Soviet states only to that between Russia and Belarus.
The People's Republic of China and Kazakhstan formed diplomatic relations on January 3, 1992. The two nations inherited a border dispute from the relations of China and the USSR, which they addressed with their first boundary agreement in April 1994, a supplementary agreement in September, 1997, and their second supplementary boundary agreement in July 1998 to mark their 1,700 kilometres (1,100 mi) shared border.
