"The ones that will suffer the most are ordinary people", Chinese Foreign Ministry spokesman Geng Shuang said.
In the latest in a series of sinister statements, the dictator's spokesman said nuclear war on the Korean Peninsula had become a matter of when, not if. "The outbreak of war is not in any side's interest".
"Through the exercise, the South Korean and USA air forces have demonstrated the alliance's strong will and capability for strong retaliation against North Korea's nuclear and missile threats", the South Korean military said in the statement, adding that the exercise also improved the two air forces' readiness to deploy "a rapid response force".
It is reported by South Korean joint chiefs of staff. North Korea's increasing nuclear and missile capability would top the agenda, it said.
Moscow also believes it is Washington's saber-rattling and regular military drills in the region that are "provoking Pyongyang into taking some rash action" after months of restraint, Russian Foreign Minister Sergey Lavrov said following the country's latest ballistic missile test. Threats from various United States officials are serving the same objective, Lavrov added.
U.S. B-1B Lancer bombers and advanced stealth fighter jets conducted joint bombing drills in South Korea on Wednesday, as a part of ongoing air drills this week with South Korea.
Yang Uk, a senior fellow at the Korea Defence and Security Forum, said B-1Bs would be key to any strike targeting major North Korean facilities.
"Several B-1B Lancer in support of F-22 Raptor conducted training maneuvers with the bombing, demonstrating the ability and determination of the allies to give a tough response to North Korea's missile and nuclear provocations", - stated in the message.
U.S. national security adviser H.R. McMaster said at the weekend the possibility of war was "increasing every day".
As tensions soar, such drills are increasingly provocative, but also increasingly risky, with the ever-present threat that North Korea will interpret a drill as a real attack and retaliate, starting a full-scale war.
On Wednesday, the U.S. ambassador to the United Nations, Nikki Haley, raised doubts about USA participation in the Olympic Winter Games in South Korea in February, telling Fox News that Washington was concerned about its citizens.
United Nations political affairs chief Jeffrey Feltman arrived in Pyongyang for a four-day visit Tuesday, the first time a high-ranking United Nations official visited the country since 2012.
Tensions on the Korean peninsula have risen markedly in recent months after North Korea's latest missile and nuclear tests, conducted in defiance of United Nations Security Council resolutions and worldwide condemnation. Some analysts and diplomats hope his visit could spark a UN-led effort to defuse tensions.
