Sharjah24 - Reuters: U.S. President Joe Biden said on Tuesday that the crisis in Ukraine was a global issue which heightened the importance of maintaining international order, territorial integrity and sovereignty.

Biden's comments delivered at the opening of the "Quad" meeting of Indo-Pacific leaders in Tokyo come a day after he broke with convention and volunteered U.S. military support for Taiwan, the self-governed island claimed by China.

"This is more than just a European issue. It's a global issue," Biden said of the Ukraine situation at the Quad meeting of the United States, Japan, India and Australia.

Biden stressed Washington would stand with its allies and push for a free and open Indo-Pacific region.

"International law, human rights must always be defended regardless of where they're violated in the world," he said.

Ukrainian President Volodymyr Zelenskiy told global business leaders in Davos on Monday that the world must increase sanctions against Russia to deter other countries from using "brute force" to achieve their aims.
