SANTIAGO, July 9 (Reuters) - Chile's President Gabriel

Boric said on Wednesday that the country has yet to formally

hear from the United States on potential copper tariffs, after

U.S. President Donald Trump the day before said he planned to

impose a 50% tariff on copper imports.

"We are waiting for the official communication from the

United States government regarding what the policy will

be-whether or not it includes copper cathodes, what the limits

are, and whether this will actually be implemented or not,"

Boric told reporters, according to local media site Emol.
