China voiced its strong dissatisfaction Wednesday against a U.S. Congress resolution on the Taiwan Relations Act saying it is an interference in its internal affairs.

"China is strongly dissatisfied and has lodged a solemn representation over the resolution adopted to commemorate the 30th anniversary of the Taiwan Relations Act," Chinese Foreign Ministry Spokesman Qin Gang said in a statement.

The U.S. House of Representatives voted for the resolution Tuesday.

The Taiwan Relations Act, passed by the U.S. Congress in 1979, required the United States to provide Taiwan with arms of a defensive character. China has never recognized the legitimacy of the act.

Qin said the Chinese government and people, from the very start, resolutely opposed the Act adopted by the United States unilaterally.

"We urge the United States to follow the basic norms guiding international relations and the three Sino-U.S. joint communiques, and stop the wrongful act of using the Taiwan issue to interfere in China's internal affairs," Qin said.
