"The overall scale of forces helps contribute to a realistic site picture for those participating, especially with regard to air assets integrating in a war-time scenario with their support personnel and equipment", the US military said.
Asked about the bomber's flight, Chinese Foreign Ministry spokesman Geng Shuang told a regular news briefing in Beijing: "We hope relevant parties can maintain restraint and not do anything to add tensions on the Korean peninsula". The U.N. did not offer detail as to the subject of the talks, but Feltman is expected to also meet foreign minister Ri and U.N. staff based in the country, the Associated Press reported. "The ones that will suffer the most are ordinary people".
Lavrov said he had passed on Pyongyang's desire for direct talks to US Secretary of State Rex Tillerson when the two met on the sidelines of a conference in Vienna on Thursday.
China's Vice Minister of Foreign Affairs Zheng Zeguang was to meet Matt Pottinger, the head of Asian affairs at the White House's National Security Council, on Thursday to discuss North Korea and trade, a senior USA official said.
The US has stepped up military pressure on North Korea considerably. "It is something that Russian Federation says it agrees with; it is something China has said it agrees with, and many other nations around the world as well", she told a regular briefing.
North Korea said that further escalation through joint drills "will only invite more bad retaliation and precipitate their self-destruction".
The aircraft entered the Korean Air Defense Identification Zone (KADIZ) over the waters south of Jeju Island and conducted simulated bombing drills over the Yellow Sea near North Korea and China, according to the official, cited by Yonhap.
North Korea launched its new Hwasong-15 missile a week ago, claiming to have achieved its goal of becoming a nuclear state.
The huge war games follow three intercontinental ballistic missile tests just days before. The Pentagon has mounted repeated shows of force after North Korean tests. The sortie prompted Pyongyang's foreign minister to warn that USA bombers could be shot down even if they did not enter North Korean airspace. Their exercise was simulated to target key North Korean facilities including nuclear and missile sites.
"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.
And now more than ever, both sides are deterred from conflict.
The weekend saw both White House national security adviser H.R. McMaster and U.S. Senator Lindsey Graham of SC say chances of war with Pyongyang were growing.
