Xi Jinping and Lee Jae Myung's Lighthearted Exchange on Espionage

During the Asia-Pacific Economic Cooperation (APEC) summit in Gyeongju, South Korea, a rare moment of levity occurred between Chinese President Xi Jinping and South Korean President Lee Jae Myung. The exchange took place on November 2, 2025, when Xi presented Lee with two Xiaomi smartphones, one intended for him and the other for his wife. As the leaders inspected the devices, Lee humorously inquired about their security, asking, “Is the communication line secure?” Xi responded with a grin, suggesting, “You can check if there’s a backdoor,” a reference to potential vulnerabilities in the phones that could allow for unauthorized access.

This lighthearted moment is significant given the backdrop of ongoing concerns regarding Chinese technology and espionage. The United States and its allies have long warned that devices from Chinese companies, including Xiaomi, could be used for spying. The U.S. government previously blacklisted Xiaomi, citing national security concerns, although the company successfully contested this designation in court. The exchange between Xi and Lee, therefore, not only showcased a rare public display of humor from Xi but also subtly acknowledged the serious implications of espionage in international relations.

The interaction was noted for its rarity, as Xi is typically reserved in public settings. Lee's spokesperson, Kim Nam-joon, emphasized that the humorous exchange reflected the growing rapport between the two leaders, stating, “If it weren’t for such chemistry, that kind of joke would not have been possible.” The two leaders engaged in multiple activities during the summit, including cultural performances and gift exchanges, which contributed to their developing personal chemistry.

While the exchange was lighthearted, it also underscored the complexities of Sino-South Korean relations amid rising tensions between China and the United States. South Korea, a key U.S. ally, faces challenges in balancing its economic ties with China against the backdrop of security concerns. The jovial interaction may serve as a diplomatic strategy to strengthen economic collaboration, even as domestic opposition in South Korea questions the alignment with China.

Despite the humor, the exchange has drawn criticism, particularly from conservative factions within South Korea. Critics argue that Lee's engagement with Xi could be perceived as aligning too closely with a country accused of espionage and interference in South Korean affairs. This sentiment echoes past concerns raised by Lee's predecessor, Yoon Suk Yeol, regarding Chinese meddling in South Korean elections.
