US President Donald Trump has warned that if his planned talks with North Korean leader Kim Jong-un are "not fruitful" he will "walk out". Trump said he will be meeting with Kim in the coming weeks to discuss the denuclearisation of the Korean Peninsula. At a joint news conference, Trump and Japanese Prime Minister Shinzo Abe said maximum pressure must be maintained on North Korea over nuclear disarmament.
