Experts: Countermoves against US justified

China has no choice but to take some countermeasures against attempts by the United States to contain its rise, experts said, though they added that the world's two largest economies must avoid relations from spiraling down as that will only harm everyone.

The comments came on the heels of recent reports by Western media outlets of a plunge in Chinese exports of gallium and germanium — two critical chipmaking minerals — to the US, following repeated moves by the US to restrict China's electric vehicle, chip and biomedicine industries.

For instance, a US bill recently proposed to bar federal contracts to some Chinese biotech enterprises, including WuXi AppTec, part of the WuXi group of companies that provide research and development as well as manufacturing services in the pharmaceutical and biotech industries.
