Proactive action to mitigate trade tensions and embrace an open global trading system is urgently needed to help the world's turbulent economy get back on track, experts said at a forum ahead of the 2019 G20 summit.

The forum, co-organized by China Daily and the Chinese Academy of Social Sciences, was held on Tuesday in Osaka, Japan.

Leaders from international institutions expect the summit to promote global economic development and improve global governance.

The International Forum for Open Global Economy was held days before the highly anticipated meeting between President Xi Jinping and United States President Donald Trump on the sidelines of the two-day summit, which begins on Friday.

Observers see the expected Sino-US meeting as a breakthrough in the contentious bilateral trade negotiations and an opportunity to ease friction.
