US President Donald Trump cast doubt on reaching a trade deal with Japan, a day after threatening higher tariffs on Japanese exports to the United States, claiming the country won’t buy American rice.

Difficult talks with many nations cast doubt on next week’s deadline. “We can do whatever we want,” Trump said.

He said Japan could face a tariff of 30 to 35 percent if no deal is made, higher than the 24 percent reciprocal tariff Trump had originally imposed, and then paused, in early April. The tariff pause ends on July 9, though Trump has touted flexibility on the deadline.
