Beijing has warned that hegemonic thinking is behind the United States Treasury Department's considering ways to restrict sensitive Chinese investments in the country's high-tech sector.

Washington has taken a slew of moves recently, and behind what the US has claimed as restrictions is actually protectionism, Foreign Ministry spokeswoman Hua Chunying told a daily news conference in Beijing on Friday.

US Assistant Treasury Secretary for International Markets and Investment Heath Tarbert told a forum on Thursday that the Treasury is mulling ways to restrict sensitive Chinese investments by invoking an emergency powers law and bringing forward some security review reforms for corporate acquisitions, Reuters reported.

Hua said the US has demanded China to further open up its market while imposing restrictions on Chinese investment in the US, a move that fails to live up to the principle of fairness and reciprocity and is an unreasonable hegemonic approach in scientific fields.

Also, the pace of China's advancing technological innovation will not be stopped because of the noise and interference, Hua added.
