Democratic Senator Robert Menendez, a Ranking Member of the Senate Foreign Relations Committee, asked, "When China retaliates', as they have said they will, what will be our next move?"
Reacting strongly to the US move, Chinese Foreign Ministry spokesman Wang Wenbin on Wednesday termed it as an "unprecedented escalation and warned retaliatory measures.
Both the US and China were locked in a political and strategic conflict in recent months on a host of issues including the origin of the coronavirus, China's decision to implement its national security law in Hong Kong and deepening trade frictions.
Beijing apparently is looking at options to order the closure of the US Consulate in Wuhan or in Hong Kong, where the Chinese officials had accused the US of backing the anti-China protests.
