Lasers have been used to target US aerial operations in the Pacific, with 20 incidents recorded since September 2017, according to a US military official.
The military spokeswoman, who requested not to be named, told CNN on Friday that lasers had been flashed at US aircraft, and that the sources of these flashes are suspected to be Chinese.
The latest incident occurred within the last two weeks, the official said.
None of the incidents have resulted in any medical complaints or injuries, the spokeswoman said.
The attacks appear similar to incidents that occurred in the East African country of Djibouti earlier in the year, when US military airmen were injured by lasers which the US military said originated from a nearby Chinese military base.
At a regular press briefing Friday, Chinese foreign ministry spokesman Geng Shuang said: "According to what we have learned from the relevant authorities, the accusations in the relevant reports by US media are totally groundless and purely fabricated."
The latest round of suspected laser attacks have all occurred in and around the East China Sea, which is home to disputed island chains, including the Senkaku, claimed by both Japan and China, where they are known as the Diaoyu.
