Use economic pressure to force North Korea to negotiate, Australia says

Julie Bishop responds to US warnings that military options remain open, saying Kim Jong-un is seeking leverage for talks

The foreign minister, Julie Bishop, has warned further pressure will be brought to bear on North Korea, as the US seeks to remind the "rocket man" that military options remain on the table.

Bishop, in New York for the UN general assembly, told Guardian Australia through her spokeswoman, there was more room to force North Korea back to the negotiating table.
