Washington: US President Donald Trump on Friday accused China of not doing enough to help contain North Korea's nuclear ambitions, after his Secretary of State Rex Tillerson said military action against Pyongyang was an option.


"North Korea is behaving very badly. They have been 'playing' the United States for years. China has done little to help!" Trump said on Twitter.
Earlier in Seoul, Tillerson said military action would be an "option on the table" if the threat posed by North Korea were to escalate.
