London (CNN Business) 1. G20 expectations: US President Donald Trump spent Friday meeting with a flurry of world leaders at the G20 summit in Osaka, including Japanese Prime Minister Shinzo Abe and Russian President Vladimir Putin.

But the big event is Trump's meeting with Chinese President Xi Jinping on Saturday.

Markets want the conversation to yield a clear truce on trade, with commitments not to escalate tensions further as Washington and Beijing work toward a final deal.

It's not clear they'll get that. Trump told journalists Friday that additional tariffs on Chinese goods remain on the table.

"We'll see what happens and what comes out of it," Trump said. "It will be a very exciting day, I'm sure. A lot of people are talking about it."
