Maritime nations are countries that have significant interests in the sea, including trade, fishing, and naval power. These nations often have extensive coastlines and rely on shipping routes for the transportation of goods. Examples of maritime nations include the United States, China, and Japan, which all have strong navies and active shipping industries. The economies of maritime nations are often closely tied to their maritime activities. They invest in ports, shipbuilding, and fishing fleets to enhance their economic growth. Additionally, maritime nations may engage in international agreements to protect marine resources and ensure safe navigation in their waters.
