South Korea in March 2026: the most important developments in politics
South Korea's politics in March 2026 was dominated by the US war with Iran and pressure to help secure the Strait of Hormuz. On March 16 the United States formally asked South Korea to join an international coalition for the strait. Foreign Minister Cho Tae-yul said the government would decide carefully and later declined to comment on a reported US request for a troop deployment. On March 17 President Donald Trump said the US no longer needed help from South Korea, Japan or NATO allies, while Marco Rubio urged South Korea to support the effort. Seoul confirmed talks with Washington on moving weapons, said it could deter North Korea even if some US assets shifted to the Middle East, and asked Iran to ensure safe passage for South Korean vessels. It evacuated citizens, considered suspending its embassy operations in Iran, and President Lee Jae-myung ordered a preemptive emergency response to economic shocks.
Relations with Japan were mixed. President Lee sought improved ties on March 1, yet South Korea called Japanese remarks reaffirming its claim to the Dokdo islands unacceptable and later urged Japan to correct its territorial claims in newly approved high school textbooks.
Domestic politics centred on the martial law investigation and corruption cases. The Navy chief was suspended for one month over allegations of involvement in a martial law plan, a special counsel team targeted former military leaders, and seven army generals were penalised. Prosecutors received the case of lawmaker Kang Sun-woo and former Seoul councilor Kim Kyung in an election bribery case, and police sought a detention warrant for the governor of North Chungcheong Province on bribery charges. Seoul Mayor Oh Se-hoon denied charges in a poll-payment case, and local elections were set for June 3.
In North Korea, Kim Jong Un was re-elected with 99.93 percent of the vote, named South Korea the 'most hostile' nation, and signed a friendship treaty with Belarus's Alexander Lukashenko in Pyongyang. Pyongyang expressed support for Iran's new supreme leader, and the UN Human Rights Council adopted a resolution on North Korean human rights on March 30.
