"China's stance on this is unswerving", Lu said in strongest comments against North Korea in the present crisis.
This week Vice President Mike Pence made an unannounced visit to the Demilitarized Zone along the border of North and South Korea, where he declared that "the era of strategic patience is over". The term "reckless" is one the North Koreans have used to describe ongoing large-scale USA and South Korean military exercises, which the North calls a dress rehearsal for an invasion.
"North Korea would do well not to test his resolve - or the strength of the armed forces of the United States in this region". "That point will probably come during this four-year term of the president", Rep. Adam Schiff, D-Calif., said in an interview on "CBS This Morning".
All of the USA military options are "terrible", said Schiff, who also said that Mr. Trump is on "very unsafe ground with all the saber-rattling". Instead, it tested a missile Sunday, which was said to have failed.
"Those who would challenge our resolve or readiness should know, we will defeat any attack and meet any use of conventional or nuclear weapons with an overwhelming and effective American response", Pence said.
Mattis credited China with trying to help get the North Korea situation "under control" with the goal of denuclearizing the peninsula.
Pence's speech on the aircraft carrier followed meetings Tuesday in Tokyo with Japanese Prime Minister Shinzo Abe, where he noted that "all options are on the table".
"When we requested to restore the agreed language that was of political importance and expressed commitment to continue to work on the draft. the USA delegation without providing any explanations cancelled the work on the draft", the Russian U.N. mission said in a statement.
"That kind of economic and diplomatic pressure will result we hope in the regime in Pyongyang forfeiting their ambitions, forfeiting their nuclear weapons program and joining the family of nations", he told CNN.
There has been some confusion over the whereabouts of a USA aircraft carrier group after Trump said last week that he had sent an "armada" as a warning to North Korea even as the ships were still far from Korean waters.
China is seriously concerned about the latest developments in the nuclear and missile programmes of the Democratic People's Republic of Korea (DPRK), Foreign Ministry spokesperson Lu Kang said.
White House Press Secretary Sean Spicer said Wednesday that China's decision to restrict coal shipments to Pyongyang was "encouraging" and said Beijing "continued to have both economic and political influence" on North Korea.
