STORY: "Their (Japan and U.S.) actions are extremely dangerous now. Japan and the U.S. are trying to conduct a war of aggression on China," said protest organiser Shunkichi Takayama, who said Biden's trip to Japan and holding the Quad summit could stoke tensions with neighbouring China.
On the second leg of his first Asia trip as president, Biden will meet with leaders of Japan, India and Australia, the "Quad," another cornerstone of his strategy to push back against China's expanding influence.
Biden is also expected to launch the Indo-Pacific Economic Framework for Prosperity (IPEF) - a programme to bind regional countries more closely through common standards in areas including supply-chain resilience, clean energy, infrastructure and digital trade.
Washington has lacked an economic pillar to its Indo-Pacific engagement since former President Donald Trump quit a multinational trans-Pacific trade agreement, leaving the field open to China to expand its influence.
