China on Monday expressed strong dissatisfaction and firm opposition after US President Donald Trump signed a government spending bill that includes provisions about China's Taiwan and Tibet Autonomous Region.

The act will seriously disrupt and hurt China-US relations, Chinese Foreign Ministry spokesperson Zhao Lijian said.

The Chinese government firmly resolves to safeguard national sovereignty and security, and strongly urges the US to stop using Tibet-related and Taiwan-related issues to interfere in China's internal affairs, he added.
