United States President Donald J. Trump on Friday said military solutions are now fully in place should North Korea act unwisely.
Trump warned North Korea it should be very nervous of the consequences if it even thinks of attacking US soil.
The warning came after Pyongyang said it was readying plans to launch missiles towards the Pacific territory of Guam.
Beijing on Friday appealed with the United States of America and North Korea for restraint, urging the two parties to be cautious with their words and actions.
Foreign Ministry spokesman Geng Shuang said in a statement that the two nations should seek to ease tensions.
