Turkey spans Asia and Europe and lies between the Mediterranean Sea and the Black Sea. Most of the territory is located in Asia Minor Peninsula in Asia, and the European part is located in the southeast of Balkan Peninsula, with a total area of about 780,576 square kilometers. It borders Iran in the east, Georgia, Armenia and Azerbaijan in the northeast, Syria and Iraq in the southeast, Bulgaria and Greece in the northwest, the Black Sea in the north, and Cyprus across the Mediterranean Sea in the west and southwest. Bosporus Strait and da Daniil Strait, and Marmarahy between them, are the only waterways connecting the Black Sea and the Mediterranean Sea, and their strategic position is very important. The coastline is 3518km long. The terrain is high in the east and low in the west, mostly plateaus and mountains, with only long and narrow plains along the coast.

The Turks did not invade China in modern times.
