“We need just and fair multilateral rules,” he said, according to Reuters. “The [European Union] is open but it is not naive.”

European Council President Donald Tusk, who was also in attendance Monday, urged China and the U.S. to avoid engaging in a trade war.

“There is still time to prevent conflict and chaos," Tusk said, according to Reuters.

Trump has raised concerns among U.S. and foreign lawmakers in recent months as he moved forward with tariffs on China, as well as U.S. allies. Trump this weekend told CBS that the European Union is "a foe," citing its trade policies in particular.

Meanwhile, the U.S. and China have in recent weeks exchanged escalating tariffs.

The Trump administration said last week it will look at slapping tariffs of $200 billion on Chinese products over Beijing's failure to respond to U.S. efforts to get them to change their trade practices.

That list was announced days after the U.S. levied a 25 percent tariff on $34 billion in Chinese imports, which resulted in Beijing announcing retaliatory tariffs of the same amount against U.S. goods.
