US Vice President Mike Pence is setting off on a big four-country Asia tour this weekend. Stops are planned in South Korea, Japan, Indonesia and Australia, amid rising tensions on the Korean peninsula and concerns about US trade policy.

Pence is scheduled to meet with heads of state and lawmakers, and hold “listening sessions” with business leaders in region.

The vice president will likely strike a reassuring tone as allies and trade partners await clarity on the Trump administration’s security and trade policy.
