U.S. President Donald Trump and British Prime Minister Theresa May agreed during a telephone call on Tuesday that China must do more to persuade North Korea to cease its missile tests, Reuters reported, citing a spokesman for May.
“The prime minister and the president agreed on the key role which China has to play, and that it was important they used all the leverage they had to ensure North Korea stopped conducting these illegal acts so that we could ensure the security and safety of nations in the region," said the spokesman.
May also said she would also work with EU leaders on further measures the EU could take to pressure the North Korean leadership, the spokesman added.
North Korea on Sunday confirmed it carried out a successful hydrogen bomb test, its sixth and most powerful nuclear test to date and the first since Trump took office.
On Sunday, Trump addressed the latest North Korean test, hinting that a military strike against North Korea was on the table. On Monday, he tweeted that an "interesting week lies ahead."
On Tuesday, North Korea warned it would send “more gift packages” to the U.S. should it continue to pressure Pyongyang.
"The U.S. will receive more gift packages from my country as long as it relies on reckless provocations and futile attempts to put pressure on the DPRK," said the North Korean Ambassador to the UN, Han Tae Song.
Sunday’s test followed threats by Pyongyang to attack Guam, a tiny U.S. territory in the Pacific.
Those threats came in response to Trump’s warning that Pyongyang faced "fire and fury like the world has never seen" if it continued to threaten the United States with its missile and nuclear programs.
