On Friday Geng said he had "confirmed reports" of the B-1B Lancers, but "details of the situation have not been determined".
The Air Force said its mission demonstrates that the USA will keep exercising the rights of freedom of navigation "anywhere worldwide law allows" and that those rights extended to military operations around the world. "China is adamantly opposed to actions that undermine sovereignty and security".
Asked about the flight by the U.S. bombers, Chinese Foreign Ministry spokesman Geng Shuang told media here that there was no problem with freedom of navigation or overflight for the East and South China Seas.
"Flying and training at night with our allies in a safe, effective manner is an important capability shared between the U.S. and Japan", said Maj.
BEIJING-The U.S. Air Force flew two bombers over the South China Sea Thursday, drawing a rebuke from China ahead of an expected meeting between the two countries' leaders.
Xi said that ties with the USA have been strained by "some negative factors" in a telephone conversation with Trump on Sunday following a flurry of controversial moves from the US.
The US flights over the South China Sea came as Trump is due to meet his Chinese counterpart Xi Jinping on the sidelines of the G-20 summit in Hamburg to discuss among others the latest ICBM test by North Korea, which could reach US state of Alaska.
"Meanwhile, bilateral relations have also been affected by some negative factors, for which the China side has expressed its position to the United States side".
The US also labeled China as one of the world's worst human traffickers and challenged Beijing in the South China Sea, by sailing close to a disputed island chain that China claims. Trump has expressed unhappiness over China not doing enough to contain its ally North Korea.
The United States believes North Korea fired an intercontinental ballistic missile on Tuesday that put parts of the USA mainland within range of Pyongyang's warheads for the first time.
