Sea-level rise and the Sea of Japan

The introduction of a market economy to Russia and to China and the attendant greater openness has encouraged Japanese local governments to promote the establishment of economic ties with the coastal regions of those countries, as well as with both South and North Korea. Local authorities have been encouraged to seek the formation of an economic bloc across the Sea of Japan or the “East Asian Sea,” as it is called by other Asian countries. Incidentally, these regions may benefit from climatic warming owing to reduced severe frost and snow environments for urbanization and industrialization.
