China's State Council Taiwan Affairs Office on Thursday urged the United States to immediately stop arming China's Taiwan region.

Chen Binhua, spokesperson for the office, made the remarks while commenting on the U.S.'s latest announcement of a package of arms sales to China's Taiwan region worth up to $11 billion.

Chen said that the Taiwan question is at the core of China's core interests and the red line in China-U.S. relations that must not be crossed, and that the U.S. announcement of the massive arms sale to Taiwan constitutes a flagrant interference in China's internal affairs.

The action has violated the one-China principle and the provisions of the three China-U.S. joint communiques, severely undermining China's sovereignty and security interests and sending a grave and wrong signal to secessionists in Taiwan.

Chen urged the U.S. side to stop condoning and supporting secessionists seeking "Taiwan independence" and to adhere to the one-China principle and the three China-U.S. joint communiques.

Chen noted that the Democratic Progressive Party (DPP) authorities' persistent attempts to look for U.S. support for their separatist agenda and seek "Taiwan independence" by force, at the cost of turning Taiwan into a "powder keg" and treating people in Taiwan as their "cannon fodder," will only bring catastrophe to Taiwan compatriots. Such acts fully expose their vicious role as "peace-breakers" and "warmongers."

Chen called on all people in Taiwan to recognize the DPP authorities' vicious nature. He also warned the DPP authorities that China's national reunification is unstoppable and that if any "Taiwan independence" separatist forces dare to cross the red line, they will surely face a decisive countermeasure.
