Why the Korea Strait matters
The Korea Strait lies between South Korea and Japan and links the Sea of Japan to the East China Sea. Busan, one of the world's largest container ports, sits on it, and it carries much of the trade between Korea, Japan, China and Russia's Pacific coast. Traffic here reflects Northeast Asian manufacturing and export activity, and it is also a route for Russian energy shipped from Pacific ports to Asian buyers.
Markets to watch
- Korean won and Korean exporters: Korea's export trade runs through Busan and the strait.
