The Panama Canal is an 82km long navigation route that connects the Caribbean Sea with the Pacific Ocean, crossing the entire country of Panama; The Suez Canal is a 163 km long waterway that connects the Mediterranean Sea with the Red Sea. These two waterways are artificial and were built to contribute to international trade because they shortened the distances that had to be traveled.
