South Korea
South Korea is a high-income economy built on manufacturing, technology and services, and a frontline state on the Korean Peninsula whose defence rests on its alliance with the United States. The issues that define it are North Korea's ballistic and nuclear missile programme, deterrence on the peninsula, and the wider standoff between the two Koreas. At home, an ageing population, housing costs and political polarisation weigh on policy, while shifts in supply chains and geopolitical competition affect its technology exports. This page holds news, politics, economy and security in South Korea, month by month, with the standing conflicts explained.
