Republicans hoping to thwart Beijing’s influence in Latin America are urging the Panamanian government to cut ties with Chinese entities.

In recent weeks, when he was President-elect Donald Trump publicly said that Panama should return the Panama Canal to the United States, and he would not rule out using military force to reclaim it. At his presidential Inauguration on Monday Trump doubled down on saying that his new administration was going to take back the canal.

They say they fought too hard to wrest it from the U.S. to now hand back the waterway, which is part of the nation’s identity.
