All options that can punish "Taiwan independence" separatist forces remain on the table, China's Ministry of National Defense said on Friday, in response to claims that the Chinese mainland could seek to justify action on Taiwan by emulating the United States' use of force to seize Venezuelan President Nicolas Maduro.

The ministry spokesman Zhang Xiaogang made the remarks at an online news conference after some foreign media outlets claimed that the costs and risks would be much higher if the mainland tried to handle the Taiwan question by copying US' moves earlier this month.

"The Taiwan question is purely China's internal affair. How to resolve it is a matter for the Chinese people, which brooks no interference from external forces," he said.

Dealing with "Taiwan independence" armed forces would be like "catching turtles in a jar", Zhang said, noting that all options that can effectively punish "Taiwan independence" separatists remain on the table.

In a separate press conference on Friday, Guo Jiakun, spokesperson for the Chinese Foreign Ministry, said China always firmly opposes countries which have diplomatic relations with China signing any agreement of sovereign implication or official nature with China's Taiwan region.

Responding to a query about a recent trade agreement between the US and China's Taiwan, Guo said the US should earnestly abide by the one-China Principle and the three China-US joint communiques.
