The Panama Canal is important to international trade because its located between the Americas so it makes travel for ships immensely less time consuming and safer. Also it overall shortens distance so it takes less fuel to make the journey from the Atlantic Ocean to the Pacific Ocean or vice versus.
The canal - a 51-mile (82-kilometre) swath through Panama - cuts thousands of miles off sea journeys between the Atlantic and Pacific Oceans. Started by the French in 1880, the US took over the construction of the canal in 1904 and completed it 10 years later. In return for rights to the waterway the US recognised Panama - which was then attempting to break away from Colombia - as a sovereign state and paid it $10m and an annuity of $250,000. During the First and Second World Wars the canal was a vital strategic artery for the United States and its allies.
