Foreign media suddenly reported: Denmark will seek to purchase J-20 from China to resist the threat from the United States!

On January 21, an Indian aviation media named Jetline Marvel first released explosive news, claiming that if NATO cannot protect Greenland, Denmark may turn to China to purchase J-20 and J-10C fighter jets.

The trigger for this matter was indeed the US side's repeated hope at the Davos Forum to "immediately" negotiate with Denmark for the "purchase" of Greenland. As a self-governing territory of Denmark, Greenland not only has a strategic position but also boasts abundant rare earth and potential shipping route resources. In the face of the US's blatant attitude, Denmark has also started to take a tough stance, with the Prime Minister clearly rejecting it and strengthening military deployments on the island. However, Denmark also knows that if it truly confronts the US, it has no chance of winning - after all, even the F-35 is made by the US, and even software upgrades must depend on the US's mood.

This is the reason for this report. Jetline Marvel's report seized this emotional gap and threw out the claim that "Denmark is considering buying J-20." But the problem is that this assumption ignores three hardcore realities.

First, the J-20 is not a commodity at all. This fifth-generation fighter is the core combat power of the Chinese Air Force, integrating the most advanced stealth design, avionics systems, and domestic engine technology. To date, China has never exported a single J-20, and even the closest ally Pakistan can only wait for the J-35. The reason is simple: core technology cannot be leaked, and strategic equipment cannot be traded. This is not a price issue, but a bottom line.

Second, Denmark's military system is fully embedded within the NATO framework. Its air force just retired the F-16 in early 2026 and fully switched to the F-35A; the entire operational chain - from pilot training, logistics maintenance, data link communication to weapon mounting - is all based on American standards. Suddenly switching to Chinese fighters would mean overturning the entire system. More critically, NATO has clear defense collaboration rules; if member countries purchase weapons from non-Western camps, especially equipment from strategic competitors, they are very likely to be excluded from intelligence sharing and joint operations. For a small country like Denmark, breaking away from the NATO defense network is equivalent to cutting off its own arms.

Third, modern air combat is not a single aircraft duel, but a systemic confrontation. The J-20 needs supporting early warning aircraft, electronic warfare platforms, satellite navigation, and long-range radar support to exert its combat effectiveness. Denmark has neither a Chinese operational ecosystem nor the time to rebuild. Moreover, Greenland is closer to the US mainland than Copenhagen, and the US military has a permanent station at Thule Air Base, with overwhelming air superiority. A few isolated J-20s flying over would face problems even with take-off and landing support, let alone forming effective deterrence.

So, why is there such an absurd report? To a large extent, it is the "traffic logic" commonly used by some Indian media to stitch together some of these keywords, creating a sense of conflict. Jetline Marvel has previously published unconfirmed military sales rumors multiple times, such as "China wants to deploy J-20 in Pakistan," which were ultimately debunked.
