New Sanctions

North Korea: Trump signs new order to widen sanctions

The US treasury has been authorised to target firms and financial institutions conducting business with the North.

The president also said China's Central Bank had instructed other Chinese banks to stop doing business with Pyongyang.

It comes less than two weeks after the UN approved new sanctions against the country over its latest nuclear test.

Tensions have risen in recent weeks over the North's continued nuclear and ballistic missile tests, despite pressure from world powers to stop.
