·The first and busiest shipping route: the North Atlantic Route. This route connects North America and Europe, the two most industrially developed regions in the world. The route starts from Quebec on the east coast of Canada, as well as New York, Boston, New Orleans, and other places in the United States, crossing the Atlantic Ocean to Europe. It then divides into two lines, north and south. The northern line enters the Baltic Sea, connecting Central and Northern European countries, while the southern line communicates with Western Europe or enters the Mediterranean Sea to reach Southern European and North African countries. One-third of the world's merchant shipping sails on this route.

·The second and most important shipping route: the Asia-Europe Route. Also known as the Suez Route due to its passage through the Suez Canal. The route starts from Northern Europe, passes through the English Channel, crosses Gibraltar and the Mediterranean Sea, then goes through the Suez Canal and the Red Sea into the Indian Ocean. After that, it also divides into two lines: heading east through the Strait of Malacca to Southeast and East Asian countries, and heading south to Australia, New Zealand, and other places. This route is the shortest connection to Western Europe. However, instability in the Middle East and pirate attacks have brought many instabilities to this route.

·The third route, with the largest oil transportation volume: the Cape of Good Hope Route. This route also starts from Northern and Western Europe, then bypasses Western North Africa via the Atlantic Ocean to the Cape of Good Hope, and then heads north to reach the Middle East. This route is not affected by the Suez Canal, and its shipping volume has significantly increased, making it the route with the largest oil transportation volume, known as the "sea warming line" for Western countries.

·The fourth route, connecting today's second-largest country and linking Central America: the North Pacific Route. The route starts from Eastern and Southeastern Asia, passes through Japan, crosses the North Pacific, and arrives at Vancouver, San Francisco, Los Angeles, and other places on the west coast of North America. With the rise of the Asia-Pacific economy, the trade volume on this route has increased year by year. However, it should be noted that this route fluctuates with seasonal changes, moving north in summer and south in winter.

·The fifth route: the South Pacific Route. This route starts from Sydney, Australia, and other places, passes through New Zealand, Honolulu, and other places, and can then reach the west coast of North America and Mexico, or head south to countries on the west coast of South America.

·The sixth route: the most important Panama Canal route for the United States. This route is a crucial passage connecting ports in the Atlantic and Pacific oceans. Ports on the west coast of the United States sail south along the Pacific, pass through the Panama Canal, and arrive at ports on the west coast of the United States, which is of great significance for connecting the east and west coasts of the United States. It is worth mentioning that the Panama Canal is also the dividing line between North and South America, and together with the Suez Canal, it is listed as one of the two most strategically significant artificial waterways in the world.

·The seventh route: the South Atlantic Route. This route starts from Western European countries, heads south across the Atlantic Ocean, and arrives at Rio de Janeiro, Brazil, Buenos Aires, Argentina, and other places on the east coast of South America. This route is also an important connection between Europe and the Americas, though the overall influence of the South American region is considerably weaker compared to North American countries.

·The last one is Russia's important shipping route: the Arctic Ocean Route. This route starts from Vladivostok in the east, heads north through the Pacific Ocean, passes through the Bering Strait, sails around the north of Russia, and reaches Murmansk, the largest port along the Arctic Ocean coast. This port is ice-free and extremely important for Russia, also being one of Russia's and the world's largest naval ports. Afterward, it reaches Northern Europe and then Western Europe, serving as a crucial route connecting Russia's east and west, and also an important sea outlet for Russia.
