Zhang Qiyue, when commenting on the warning, expressed China's strong dissatisfaction and firm opposition to the announcement.

"The Chinese side demands that the US correct their mistake immediately and take measures to counter the negative impact brought about by the so-called warning,'' said Zhang.

The US State Department claimed on Thursday that at least two Americans had been detained by China for charges of espionage and activities endangering China's national security.

It warned US citizens, particularly those of Chinese descent and those engaged in activities criticizing China or in contact with the Taiwan authorities, that they face the risk of being detained if they go to China.

China has always welcomed foreigners, including those from the United States, to visit China and has protected their legitimate rights according to law, said Zhang.

But she pointed out that foreigners should abide by China's laws during their stay in the country.

Zhang said the US side knows full well that a few Americans are being handled according to Chinese law because they have broken the law.

She criticized the United States for their unwarranted criticism of the Chinese judicial organ's lawful handling of the relevant cases, for fabricating so-called risks and for attempting to incite Chinese Americans, as well as other people, against China.
