Yesterday we reported how Kim Jong-un was said to be willing to sit down with its sworn enemy the to hash out a deal that would see a freeze on future tests .
The news of the new test also comes as another US official said Wednesday there are signs of increased activity at North Korea’s lone nuclear test site.
“There are more people and more cars but nobody knows what that means,” said the official.
North Korea has conducted five nuclear tests since 2006 , including two last year.
President Trump had hoped China would help deescalate tensions in the region following a series of ballistic missile tests.
But the US leader hinted this week that Beijing had failed to reign in Kim Jong-un.
“While I greatly appreciate the efforts of President Xi & China to help with North Korea, it has not worked out. At least I know China tried!” said Trump in a tweet earlier this week.
At the State Department, Secretary of State Rex Tillerson and Defense Secretary Jim Mattis hosted Chinese counterparts.
“China understands that the United States regards North Korea as our top security threat,” Tillerson told reporters Wednesday.
“We reiterated to China that they have a diplomatic responsibility to exert much great economic and diplomatic pressure on the regime if they want to prevent further escalation in the region.”
