In a world increasingly fragmented by U.S. President Donald Trump's "America First" agenda, Japan should take on the role as the world's new "stabilizer" by committing to the landmark Paris accord on climate change and keeping a multilateral trade regime from falling apart in the absence of the United States, according to experts who gathered at a Tokyo conference earlier this week.

The annual G1 Global Conference, held at Globis University in Tokyo, examined Japan's shifting roles on the global stage on the heels of an intensifying trade war between the U.S. and China that its panelists said has thrown the international order into disarray.

The conference held Sunday invited experts on fields including security, energy and technology — as well as social entrepreneurs and business executives — to discuss a "fractured world" caused by the rise of protectionism, the shift in Asian geopolitics and potential threats stemming from the advent of artificial intelligence.
