BEIJING — China's top diplomat in Hong Kong has met the senior US diplomat in the city to protest against a US public alert over new security rules in Hong Kong, the Chinese Foreign Ministry said.

In a statement released late on Saturday (March 28), the Chinese foreign ministry's Hong Kong office said Commissioner Cui Jianchun met US Consul General Julie Eadeh on March 27 and expressed "strong dissatisfaction and firm opposition", urging Washington to stop interfering in Hong Kong's affairs and China's internal affairs "in any form".
