BEIJING, June 3 (CGTN) -- The Chinese Ministry of Culture and Tourism issued a warning to its citizens on Tuesday to exercise caution before going to the U.S. for tourist visits.

This alert comes after recent criminal cases including mass shootings, robberies and thefts occurred in the U.S.

The Chinese Ministry of Foreign Affairs (MOFA) also reminded Chinese citizens to improve safety awareness and stay alert when visiting the U.S., said a spokesperson on Tuesday in a regular press briefing.

Beijing's response comes after reports that Chinese citizens were allegedly harassed by U.S. authorities during their entry and exit checks, said the spokesperson.
