The port is one of the five busiest ports in the world. The World Bank has praised Singapore as the easiest place in the world to do business and ranks Singapore the world's top logistics hub.
The country is also the world's fourth-largest foreign-exchange trading centre after London, New York and Tokyo. Singapore is a very diverse and young country. It has many languages, cultures and religions for a country its size. Due to the many different languages and cultures in the country, there is no single set of culturally acceptable behaviours.
