A Chinese mainland spokeswoman on Wednesday denounced upcoming plans for a political and military dialogue between the United States and Taiwan, saying it will only bring disaster to the island.

Zhu Fenglian, a spokeswoman for the Taiwan Affairs Office of the State Council, said on Wednesday that the mainland has always firmly opposed any form of official exchanges or military contacts between Taiwan and the US.

The US State Department will hold a video conference with Taiwan on Thursday that is expected to cover topics such as regional developments, Taiwan-US military cooperation and arms sales.

The spokeswoman urged the US to abide by the one-China principle and the provisions of the three China-US joint communiques and stop sending wrong signals to the "Taiwan independence" separatist forces.

"By relying on the US to seek independence, the ruling Democratic Progressive Party authorities are willing to act as pawns, which will only bring deep disaster to the island," she said.
