BEIJING, Sept. 29 (Xinhua) -- The Chinese mainland is resolute to curb any attempts by Taiwan’s Democratic Progressive Party (DPP) authority to collude with the United States and seek "Taiwan independence", said a mainland spokesperson Wednesday.

Zhu Fenglian, a spokesperson for the Taiwan Affairs Office of the State Council, made the remarks when commenting on the U.S. proposal to have Taiwan participate in the 2022 Rim of the Pacific military exercises, which is included in the National Defense Authorization Act for Fiscal Year 2022 passed by the U.S. House of Representatives recently.

The Taiwan question is entirely China’s internal affair, and the U.S. government and its relevant bodies have no right to interfere in it, emphasized Zhu.

Zhu also warned the DPP authority not to misjudge the situation. "Any attempt to seek ‘Taiwan independence’ by relying on external forces is doomed to fail," Zhu said.
