The owners of Mercedes have said they have no idea how Kim Jong-un got hold of their armoured vehicles to use for his trips abroad.
The North Korean leader raised eyebrows using the German-made stretch limousines at several high-profile summits over the past two years.
Sales of luxury goods, including limousines, are banned under UN sanctions aimed at pressuring the nation to denuclearise.
But when Kim met with Russian President Vladimir Putin this week, he had two Mercedes Maybachs waiting for his arrival.
He is believed to have also used one of the cars for his summits with Donald Trump in Singapore in June last year and in Hanoi in February.
Daimler, which owns Mercedes, has said it has no idea where he got them and has no business dealings with the isolated country.
Their spokesperson Silke Mockert said: We have absolutely no idea how those vehicles were delivered to North Korea.
For Daimler, the correct export of products in conformance with the law is a fundamental principle of responsible entrepreneurial activity.
Daimler, based in Stuttgart, Germany, is one of the worlds biggest and prestigious car companies.
On its home page, the multinational giant boasts of selling vehicles and services in nearly all the countries of the world and of having production facilities in Europe, North and South America, Asia and Africa.
