BEIJING, May 18 (Xinhua) -- China on Wednesday urged the United States to revoke a recent "Concurrent Resolution" reaffirming the Taiwan Relations Act and the Six Assurances as the cornerstone of U.S.-Taiwan relations.

China urges U.S. to revoke Concurrent Resolution on Taiwan.

Foreign Ministry spokesperson Hong Lei said at a routine press briefing that the United States should take effective measures to eliminate the negative effects of the Concurrent Resolution.

The U.S. House of Representatives passed the Concurrent Resolution on Monday. Hong said China is firmly opposed.

"The so-called Taiwan Relations Act and Six Assurances seriously violate the one-China policy and the principles of the three China-U.S. Joint Communiques," Hong said, accusing the United States of interfering in China's internal affairs.

He urged the United States to abide by the commitment to oppose "Taiwan independence."

In 1982, then-U.S. President Ronald Reagan issued the Six Assurances, which stipulated that the United States would not "formally recognize Chinese sovereignty over Taiwan."
