President Trump is planning on opening a new front in his ongoing trade war: Japan. The president said Thursday he wants to renegotiate trade policy with them and expects that they won’t be happy with his opening offer.

“Mr. Trump described his good relations with the Japanese leadership but then added: ‘Of course that will end as soon as I tell them how much they have to pay,'” Wall Street Journal columnist James Freeman wrote Thursday, recounting a personal call he received from the president. Freeman had offered qualified praise for Trump’s policies in a TV appearance earlier in the day.
