Disputes over the South China Sea are back in the news, with China and the Philippines both marking out areas they say are theirs. China has previously been accused of hitting Philippine boats with water cannon and both sides say the other have rammed boats into each other.

Benny Lu from the BBC’s Chinese service in Hong Kong takes us through the background of it all and explains how the US’s relationship with China fits into it, especially with Donald Trump’s re-election.

It’s not just China and the Philippines arguing over this area. BBC Vietnamese reporter Thuong Le explains Vietnam’s involvement in the ongoing disputes, which even led to the Barbie movie being banned in Vietnam last summer.

Plus, we hear from people we spoke to in Manila when What in the World visited the Philippines, on why they feel strongly about the issue.
