Chinese People's Political Consultative Conference (CPPCC) member Andy Tsang on Wednesday slammed the US move to slap additional tariff on Chinese exports because of the fentanyl crisis.

Tsang, deputy director of the National Narcotics Control Commission and a former Hong Kong police commissioner, made the comments in Beijing on the sidelines of the "Two Sessions" after US President Donald Trump imposed an additional 10 percent tariff on China, citing a lack of progress on tackling fentanyl.

Tsang said Beijing will study countermeasures and the move should not affect anti-drug cooperation.

He added that he believes China is one of the world's best performers in drug-control efforts.

Former health minister and CPPCC delegate Ko Wing-man, meanwhile, said the setting up of Hong Kong's third medical school aims to strengthen medical education and research capabilities, not just addressing doctor shortages.

Separately, another CPPCC member and former Bar Association chairwoman Winnie Tam said she hopes the Greater Bay Area will recognise Hong Kong's potential to help train professionals in foreign-related legal matters.

Tam, who chairs the Communications Authority, also said her team will continue to improve anti-fraud measures and work more closely with different platforms.
