BEIJING, Jan. 30 (Xinhua) -- The Chinese mainland firmly opposes any external intervention on the Taiwan question which concerns the country's core interests, a mainland spokesperson said Wednesday.

Ma Xiaoguang, spokesperson with the State Council Taiwan Affairs Office, made the comment at a press conference, in response to the passage of two U.S. military vessels through the Taiwan Strait on Jan. 24.

"We have the resolve, confidence and ability to safeguard China's sovereignty and territorial integrity," Ma said.

When asked to comment on the Democratic Progressive Party's (DPP) recent behavior of trying to seek foreign intervention and professing that the mainland had "suppressed and dwarfed" Taiwan, Ma said Taiwan's DPP administration had constantly fanned hostility across the Strait, obstructed exchanges and cooperation between people on the two sides, and undermined the peaceful development of cross-Strait relations.

"The DPP has put the rights and interests of people from Taiwan at stake only for its own ends," Ma said.
