Japanese Prime Minister Shigeru Ishiba went into his first summit meeting with US President Donald Trump amid concerns in Tokyo that Japan could be next in the firing line of US allies after Canada and others.

After a Japan-US summit meeting in Washington D.C., Japan’s prime minister Shigeru Ishiba has expressed his intention to invest $1 trillion into the United States — an “unprecedented” level, according to the PM.

U.S. President Donald Trump welcomed Japanese Prime Minister Shigeru Ishiba at the White House on Friday and said the two countries would work to cut Washington's trade deficit with Tokyo amid escalating trade tensions threatening to rupture the global economy.
