HONG KONG — China has warned its citizens about traveling to a foreign country with “highly frequent” gun violence.

That oh-so-dangerous place? The United States.

The notice, issued by the Chinese Embassy in Washington on Saturday, was China’s latest effort to warn tourists about a land where gun violence kills about as many people as car accidents — a rate that far exceeds that of any other rich nation.

The notice also said robberies and burglaries were common in the United States, and warned Chinese tourists to be cautious of “suspicious” people there. “Avoid going out alone at night,” it added. “If in danger, please be calm and call 911.”

Some social media users in China took the warning to heart.

“Just a gentle reminder to everyone: The U.S. is not safe,” one user wrote on Sina Weibo, a Twitter-like microblogging service.
