BRUSSELS: European Commission chief Jean-Claude Juncker said US efforts to split the EU on trade “are in vain,” in a message yesterday to President Donald Trump before their talks in Washington next week, reports AFP.

Juncker, who heads the powerful executive arm of the 28-nation European Union, will visit the White House on July 25 to try to convince Trump to drop tariffs on metals and avoid further duties on cars.

He told a press conference that he “would like to make the US president understand” a key point on trade while admitting he had tried unsuccessfully with him before.

“The European Union and its single market are indivisible,” the former Luxembourg premier said when asked about Trump’s bid for bilateral deals. “All the efforts to divide the Europeans are in vain,” Juncker said.

“It seems to me all these efforts to have bilateral ties, which must take place between our partners and the commission and therefore the EU, must be better explained,” he added.

“I go there calmly,” he said.

The Commission said Juncker and Trump will focus on improving transatlantic trade and forging a stronger economic partnership.
