The combined B-1 and F-22 drill represents a step up in the normal tit-for-tat between the USA and North Korea. The president then announced the Wednesday after that he had already spoken to China's President Xi Jinping and that "major sanctions" would be imposed on North Korea.
A state-run newspaper in northeastern China's Jilin city, which is near the border with North Korea, published a full page of "common sense" advice that was meant to keep its readers alive in the case of attack. The Pentagon has mounted repeated shows of force after North Korean tests.
China, North Korea's neighbour and lone major ally, has again urged calm and says war is not the answer as Pyongyang said military drills involving the US and South Korean forces made war "an established fact".
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.
But with the U.S. using its best planes to message North Korea, and Pyongyang demonstrating missiles that experts assess can hit anywhere in the United States, it's unclear just how much higher tensions on the Korean Peninsula could escalate.
The United States and South Korea deployed THAAD, a US missile defense system, that is strongly opposed in Beijing.
"B-1B bombers have been regularly dispatched to the Korean peninsula over the past years; however, it seems that the US Air Force might have enhanced its training to better prepare for actual warfare", he said.
Both sides insist they don't want war, while saying they will act to defend themselves.
The warplanes simulated land strikes at a military field near South Korea's eastern coast.
The New York Post quoted physicist David Wright, who estimated that the missile could have traveled 8,100 miles and would have "more than enough range to reach Washington, D.C., and in fact any part of the continental United States".
The rising tensions coincide with a rare visit to North Korea by United Nations political affairs chief Jeffrey Feltman, the highest-level UN official to visit North Korea since 2012.
Meanwhile China, North Korea's neighbour and lone major ally, again urged calm and said war was not the answer.
