Early relations with the People's Republic of China were cold due to China's veto at the United Nations Security Council to block Bangladesh's accession to the United Nations. Lately however China has made efforts to improve relations with many of its neighbors. Trade with China reached a record level in 2006 of $3.2 billion under the auspices of the Asia-Pacific Trade Agreement (AFTA). The trade balance between the two countries are in China's favour. China has also officially agreed to helping Bangladesh on developing their nuclear power plant. Bangladesh has also signed the Apsco convention with six other nations to form a pact with China on space exploration.
