This is a radio conversation of a US naval ship with Chinese authorities off the coast of Vietnam in South China Sea in October 1980. Presumably a true story.

Chinese: Please divert your course 15 degrees to the south to avoid a collision.
Americans: Recommend you divert your course 15 degrees to the north to avoid a collision.
Chinese: Negative. You will have to divert your course 15 degrees to the south to avoid a collision.
Americans: This is the captain of a US Navy ship. I say again, divert YOUR course.
Chinese: No, I say again, you divert YOUR course.
Americans: This is the Aircraft Carrier USS MIDWAY, the second largest ship in the United States Pacific Fleet. We are accompanied with three Destroyers, three Cruisers and numerous support vessels. I DEMAND that you change your course 15 degrees north. I say again, that’s one-five degrees north, or counter-measures will be undertaken to ensure the safety of this ship.
Chinese: This is a lighthouse. You are on the course to collide with a Vietnamese fishing boat filled with hundreds refugees!
