"The Chinese side is firmly opposed to the arms sales by the US to Taiwan. This position is steadfast, clear and consistent. The aforementioned act constitutes a grave breach of the spirit of the three joint communiqués between China and the US, especially that of the August 17 Communiqué," Chinese Foreign Ministry Spokesperson Qin Gang was quoted as saying in a statement issued on Friday.
The three joint communiques signed between China and the United States in 1972, 1979 and 1982 represent mutual statements aimed at improving US-China relations. According to the 1982 communique cited by Qin, the United States pledged to gradually curtail arms sales to Taiwan.
In his comments Qin called on the United States to cease selling arms to Taiwan and instead contribute to the furthering of US-China relations.
The sale of the warships to Taiwan was agreed to by US President Barack Obama on Thursday.
