The Chinese Embassy in Washington issued a security advisory last week, warning Chinese citizens traveling to the US that "shooting, robbery, and theft are frequent." Tourists were also warned to "be alert to suspicious people around you, avoid going out alone at night."

In addition to getting killed and mugged, the embassy warned Chinese tourists to be aware of issues including expensive medical bills, searches and seizures by customs agents, telecommunications fraud and natural disasters.

Further trolling the US, the alert published on the embassy's website last Thursday said that "public security in the United States is not sufficient. Cases of shootings, robberies, and theft are frequent."

Commenting on the notice, China's Foreign Ministry said summer is usually the peak season for Chinese citizens to visit the US and that it was the Chinese Embassy's duty to warn tourists about potential risks in the country, in response to questions over if the warning is related to the tensions between China and the US.
