Amilitary tactic through which ports are shut off to keep people or supplies from moving in or out

A military tactic through which ports are shut off to keep people and or supplies from moving in or out is called a blockade. A blockade is usually directed at an entire country or region and is  different  from a siege which targets a fortress or a city. It is also distinct from  an embargo or sanctions, which are actually legal barriers to trade.

While most blockades in history took place at sea , blockades were also used on land to prevent someone from coming into a certain area. In the 20th Century, air power has also been used to enhance the effectiveness of the blockade by halting air traffic within the blockaded airspace.

well the fact it is basically a peninsula allowed trade to come from many places, thus allowing cultural diffusion to take place. india has seasonal monsoons that merchants travel back and forth from india using the monsoons wind patterns
