North Korea could soon increase the cost of visiting the country by changing the currency it uses for tourism payments to the U.S. dollar, according to a company specializing in tours to the DPRK.

In a post uploaded on its website on Wednesday, Young Pioneer Tours stated that its “partners in North Korea and beyond” have indicated the DPRK will change its preferred currency for settling tour company accounts from euros to dollars, which is already known to be the dominant foreign currency in use in the country.
