North Korea’s Songdowon International Children’s Camp has welcomed hundreds of Russian and Chinese kids as it kicked off its summer season on the DPRK’s east coast, two months after the U.K. blacklisted the institution over claims of indoctrination of Ukrainian youth.

More than 400 Russian schoolchildren joined the camp’s first session of the year, which began on Sunday, Primorsky Krai’s Ministry of International and External Economic Relations said in a social media post on Tuesday.
