Washington, Sep 6 (PTI) US President Donald Trump discussed the latest nuclear test by North Korea this week with the British and Australian leaders as part of his outreach to global leaders, the White House said today.
Earlier Wednesday, the United States proposed a resolution at the UN that would include broad new sanctions on North Korea and freeze the assets of leader Kim Jong Un in the wake of global concern over the rogue nation's nuclear weapons tests.
On his way to Bismarck, North Dakota, where he'll participate in a tax reform event, Trump told reporters that military action against the Democratic People's Republic of Korea (DPRK) was "not a first choice, but we will see what happens". But, he indicated, other avenues for pressure would come first.
The White House said Donald Trump and Mr Turnbull "confirmed that their two countries will intensify joint efforts to denuclearise North Korea".
