Europe, Japan and Canada hope a G7 meeting in Italy this week will give them a better picture of U.S. President Donald Trump's direction on key policies that he has yet to spell out.

The official agenda for Group of Seven finance ministers and central bankers in the city of Bari from Thursday to Saturday focuses on inequality, international tax rules, cybersecurity and blocking the funding of terrorism.

However, many participants will be looking to Treasury Secretary Steven Mnuchin to gauge U.S. intentions on issues where Trump has threatened to upset the group's consensus: protectionism and climate change.
