BEIJING - A Chinese mainland spokesperson on Thursday slammed the so-called "Taiwan Allies International Protection and Enhancement Initiative (TAIPEI) Act of 2019" passed by the US House of Representatives recently, saying the passage of the Taiwan-related bill is "unreasonable."

The Taiwan-related bill of the US Congress blatantly obstructs other countries from establishing diplomatic ties with China, abets Taiwan in expanding the so-called "international space," said Zhu Fenglian, spokesperson for the State Council Taiwan Affairs Office, when responding to a query about the act passed by the US House of Representatives.

China firmly opposes the US side interfering in its internal affairs by any form, as well as sabotaging the one-China principle and the three China-US Joint Communiques

The Ministry of Foreign Affairs had made clear its solemn position on the US House's passage of the Taiwan-related bill, Zhu said, reiterating that China firmly opposes the US side interfering in its internal affairs by any form, as well as sabotaging the one-China principle and the three China-US Joint Communiques.

In the recent period, the US Congress has repeatedly manipulated the so-called Taiwan-related bill, which would only provoke more disputes between the two sides of the Taiwan Strait, create more troubles for China-US relations, and end up harming the interests of the United States itself, she said.

The unceasing attempts of Taiwan's Democratic Progressive Party authority to add to their self-importance by soliciting foreign support will only aggravate tensions and turbulence in cross-Strait relations and undermine cross-Strait peace and stability, Zhu said.
