The warning comes amid an increasingly bitter trade dispute between Beijing and Washington and tougher immigration enforcement by the Trump administration.

In a separate warning, China's foreign ministry said U.S. law enforcement agencies have "repeatedly" used methods such as immigration and on-site interviews to "harass" Chinese citizens in the US.
Chinese citizens and companies in the USA risk "harassment" from law enforcement authorities and should also be wary of increased violent crime, Beijingsaid in two travel alerts issued Tuesday amid escalating trade tensions between the two countries. But it said the United States was "disappointed" by the report Beijing issued over the weekend defending China's stance and accusing US officials of backsliding in the talks.
The tourism ministry also warned Chinese tourists of potential threats such as robbery and gun violence while visiting the United States, state media said.
The US reignited the trade war last month by raising tariffs on billions of dollars worth of Chinese goods, prompting Beijing to retaliate.
They are "urged to learn about the information about the public security situation and related laws and regulations of tourist destinations, to raise safety awareness and step up precautions to stay safe".
In a statement, the Trump administration also accused China of "backpedalling" on trade agreements. "So it is only necessary for us to issue such a notice".
On June 2, the Chinese regime released a white paper outlining its position in the trade talks, in which it cited three alleged instances in which the United States backtracked on commitments made during negotiations.

On Tuesday, China rebuked U.S. Secretary of State Mike Pompeo over his remarks on China's human rights records ahead of the 30th anniversary of the Tiananmen Square protest, during which communist authorities killed an unknown number of student demonstrators.
In early May, the two nations put a halt over their talks when USA accused Beijing of backtracking on commitments to codify in law changes to its intellectual property and technology transfer practices to address United States demands.
"The United States is disappointed that the Chinese have chosen in the "White Paper" issued [on Sunday] and recent public statements to pursue a blame game misrepresenting the nature and history of trade negotiations between the two countries", the statement said.
These practices, it says, have hurt American workers and businesses. and led to a trade deficit a year ago of nearly 420 billion USA dollars.
Last year, the number of Chinese tourists visiting the U.S. fell for the first time in 15 years, after more than a decade of rapid growth, amid the trade friction between the two countries.
