Seoul. South Korean officials on Thursday said providing Samsung smartphones to North Korean athletes at the Paris Olympics would violate UN Security Council sanctions against the country over its nuclear and missile program.

The South Korean technology giant is a major Olympic partner, and its newest Galaxy Z Flip 6 smartphones are being given to all athletes competing at the Games.

The International Olympic Committee confirmed that the phones were sent to the Olympic village, then later said the North Korean athletes had not received them. It's unclear where the phones might have gone.

South Korea’s Foreign Ministry said smartphones are among the items banned under Security Council Resolution 2397 passed in 2017, which prohibits the supply, sale or transfer to North Korea of “all industrial machinery.”

The resolution doesn’t make a distinction between North Korea’s government and its people, and South Korean officials made clear that smartphones would be banned however they entered the country.

Lee Jaewoong, the ministry’s spokesperson, said it would be “critical to prevent the prohibited items from going into North Korea.”

He said the Seoul government was making “necessary diplomatic efforts” to ensure sanctions are upheld but refused to provide details.

The issue also arose during the 2018 Winter Olympics in South Korea, where the North Koreans refused to receive Samsung devices that the organizing committee had offered under the condition that they return them before heading home, according to South Korean officials.

North Korea sent 16 athletes to the Paris Games to compete in seven sports, including wrestling, swimming, table tennis and boxing.

North Korea did not participate in the 2020 Summer Games in Tokyo in 2021 because of the country's self-imposed lockdown during the coronavirus pandemic. The IOC then barred the country from participating in the 2022 Winter Games in Beijing as punishment for refusing to send a team to Tokyo.
