Seoul: South Korea and Taiwan have officially closed their diplomatic missions in each other's capitals as South Korea formally shifted its diplomatic recognition from Taiwan to China. This move marked a significant change in the diplomatic landscape for the region.

According to Yonhap News Agency, the closure in 1992 followed South Korea's decision to establish formal diplomatic relations with China, reflecting the increasing global recognition of China's growing influence. The shift in diplomatic relations was seen as a strategic move by South Korea to align with the economic and geopolitical power of China.
