By sea: South Korea has several major ports, including Busan, Incheon, and Gwangyang, which are connected to many other countries by regular ferry services.
By land: South Korea has land borders with North Korea and China. There are several border crossings between North and South Korea, but they are mostly closed due to the tense relations between the two countries. The only open border crossing between North and South Korea is the Panmunjom Truce Village, which is located in the Demilitarized Zone (DMZ). There are also several border crossings between China and South Korea, which are open for trade and travel.
By train: There is no direct train service between South Korea and any other country. However, there are plans to build a high-speed rail line that will connect South Korea to China, Japan, and Russia.
