China announces an 84% tariff on US imports, to take effect on Thursday, after Donald Trump imposed a 104% tariff on Chinese goods entering the US. We'll hear from South Korea and from Germany on what they can do to protect themselves.

Also on the programme: The people of Myanmar, ignored and desperate after the earthquake; as the BBC puts a restored sculpture back on display, can you separate great art from appalling artists? And we'll hear from a British woman who has been reunited with a "talking postcard" - also known as a "voice-o-graph" - she recorded in New York 70 years ago.
