Such a defiant move was likely to draw even more pressure from the USA which ordered its nuclear-powered USS Carl Vinson aircraft carrier strike group to the region, Lu told the Hong Kong-based South China Morning Post.
Submarines also regularly provide undersea cover for carrier strike groups.
Sergey Lavrov is responding to Vice President Mike Pence's statement Monday in South Korea that the "era of strategic patience is over" with regard to North Korea's efforts to build nuclear weapons.
"The US is coordinating with the South Korean government about a combined drill which the Carl Vinson Strike Group can join", a South Korean official said. That's a fact, it's happened.

A Reuters reporter covering the Pentagon first reported April 9 that the Vinson strike group was headed toward the Korean peninsula, citing an unnamed USA official. As the New York Times reports, a few ships are not where the Trump White House said they were.

Trump has stated that all options, including military action, are possible as North Korea continues to develop its ballistic missile and nuclear weapons program. "We've made no such statement", said one official.

Vice President Mike Pence, who called the latest missile test a "provocation", is now in South Korea to meet with USA and South Korean military.
The vessel left the city-state on April 8. He says the Trump administration's plans to simplify the US tax code and cut the corporate tax rate will "benefit every business represented here today".
North Korea did not refer to the mix-up but said the United States and its allies "should not mess with us". The Carl Vinson is accompanied by a destroyer ship with an Aegis combat system to track and intercept missiles.
