The secretive state announced it was pulling out of high-level talks with South Korea scheduled for tomorrow for the same reason, the Seoul-based Yonhap news agency reported.
Kim Jong-un is due to meet with President Trump in Singapore next month for a historic summit aimed at bringing peace to the Korean Peninsula by curbing the North’s nuclear weapons programme.
If it goes ahead, the meeting will be the first time a sitting US president has come face-to-face with his North Korean counterpart.
The hermit kingdom has now cast doubt over whether the talks will take place, but US officials say they have heard nothing from Pyongyang.
North Korea has threatened to cancel the scheduled summit between Kim Jong-un and President Trump
North Korea said the ongoing ‘Max Thunder’ drills carried out by American and South Korean air power was a rehearsal for invasion.
It also labelled the exercises a deliberate provocation.
The two-week exercise began on Friday (May 11) and involves some 100 warplanes.
North Korea’s puppet state media said: “This exercise targeting us, which is being carried out across South Korea and targeting us, is a flagrant challenge to the Panmunjom Declaration and an intentional military provocation running counter to the positive political development on the Korean Peninsula.
“The United States will also have to undertake careful deliberations about the fate of the planned North Korea-US summit in light of this provocative military ruckus jointly conducted with the South Korean authorities.”
The US State Department said it had not heard anything from North Korea over the possible cancellation of the summit.
Officials said they were continuing to make preparations for the June 12 talks.

North Korea has used similar language before in the build-up to and after joint US-South Korea drills.
Tomorrow’s talks between the two Koreas were supposed to follow-up on a successful meeting between Kim and South Korean President Moon Jae-in last month.
High-level officials from both sides of the demilitarised zone had been scheduled to meet in the truce village of Panmunjom.
North Korea last week released three Americans who were being held prisoner by Kim’s regime.

The rogue state has also announced it would decommission its main nuclear test site as a gesture of goodwill ahead of the planned summit with President Donald Trump.
Thanking Kim’s regime via Tweet last week, Mr Trump said: “North Korea has announced that they will dismantle Nuclear Test Site this month, ahead of the big Summit Meeting on June 12th.
“Thank you, a very smart and gracious gesture!”
The US leader had previously taken to Twitter to announce the details of his upcoming meeting with Kim.
He wrote: “The highly anticipated meeting between Kim Jong-un and myself will take place in Singapore on June 12th.
“We will both try to make it a very special moment for World Peace!”
