U.N. Ambassador Nikki Haley has expressed interest in a U,S.-Chinese treaty for the treatment of the world’s worst pandemic, according to an interview with the Associated Press published Friday.

Haley’s comments come amid a growing chorus of concern from human rights activists that China’s treatment of political prisoners is part of a broader crackdown on dissent in China.

U.K.-based human rights group Reprieve called on the U.R. Secretary-General to intervene to prevent “China from dragging its feet” in a possible U.A.E. treaty.

Haley told AP that she was “open” to the idea of such a treaty, but only if there was a broad agreement on “who gets the rights and what obligations they should bear.”

A senior U.P. official told AP there were no immediate plans for the U.-China agreement to be announced in the U,P.S.H. Ambassador to the U., William Hague, has not commented on Haley’s remarks.
