The G20 summit has kicked off in Osaka as Japan's Prime Minister Shinzo Abe welcomed world leaders. The goal of the summit is to reach a consensus on a wide range of pressing issues -- despite conflicting views and competing interests.
There are four sessions planned.
Topics include the global economy, digital innovation, women's empowerment and the environment.
But trade is expected to dominate discussions -- largely due to the United States shifting its approach under President Donald Trump.
Trump's preference for bilateral deals and his complaints that other countries are taking advantage of the US has disrupted international trading norms.
And as the US and China continue to butt heads on a trade deal, there are growing concerns the economy could sag if the G20 leaders do not present a unified front.
