On the final day of his high-stakes strip to Asia, President Joe Biden urged international leaders in Japan to do more to stop Russia’s invasion of Ukraine and said there would be no change to "strategic ambiguity" on Taiwan, a day after frustrating China when he suggested the U.S. could send troops to the region.

"This is more than just a European issue. It's a global issue," Biden said of the Russia-Ukraine War Tuesday, alongside leaders of Japan, India and Australia.

In his remarks, Biden described the Eastern European war as a "dark hour" in history.

"We’re navigating a dark hour in our shared history," the U.S. president said. "The Russian brutal and unprovoked war against Ukraine has triggered a humanitarian catastrophe and innocent civilians have been killed in the streets and millions of refugees are internally displaced as well as in exile."

He added: "The world has to deal with it, and we are."

WHAT BIDEN'S TAIWAN COMMENTS MEAN FOR CHINA AND THE US

Biden did not specifically name any of the countries present at the summit, but his comments appeared to be directed at Indian Prime Minister Narendra Modi as India has failed to implement any sanctions against Russia.

The Russia-Ukraine War is taking place at a time when tensions between China and the neighboring island of Taiwan continue to rise and experts say China could be considering military action.

Biden was asked by a group of reporters at the summit if he stood by comments he made Monday, that the U.S. was still considering the possibility of sending troops near Taiwan to stop a potential invasion by China, which drew criticism by the latter country.

"No," Biden answered, Reuters reported. "The policy has not changed at all. I stated that when I made my statement yesterday."

"Are you willing to get involved militarily to defend Taiwan if it comes to that?" Biden was specifically asked during a news conference.

"Yes," Biden answered. "That's the commitment we made."

The initial comment on Monday drew backlash from Biden’s opponents and officials in Beijing, some of whom suggested he misspoke.

A potential conflict in the East China Sea was not a part of the Quad Summit’s agenda items.

President Biden returns to Washington Tuesday.
