Klang is a city in which of these countries?

Klang or Kelang, is a royal town and former capital of the state of Selangor, Malaysia. It is located within the Klang District. It was the civil capital of Selangor in an earlier era prior to the emergence of Kuala Lumpur and the current capital, Shah Alam. Port Klang, which is located in the Klang District, is the 12th busiest transshipment port and the 12th busiest container port in the world.

In the 19th century the importance of Klang greatly increased by the rapid expansion of tin mining as a result of the increased demand for tin from the West. Until the construction of Port Swettenham (now known as Port Klang) in 1901, Klang remained the chief outlet for Selangor's tin, and its position was enhanced by the completion of the Klang Valley railway to Bukit Kuda in 1886. In the 1890s its growth was further stimulated by the development of the district into the State' leading producer of coffee, and later rubber. In 1903, the royal seat was moved back to Klang when it became the official seat of Sultan Sulaiman.

Rubber used to be an important part of the economy of the region, but from the 1970s onwards, many rubber plantations have switched to palm oil, and were then converted again for urban development and infrastructure use.

As of 2010, the Klang City has a total population of 240,016 (10,445 in the city centre), while the population of Klang District is 842,146, and the population of all towns managed by Klang Municipal Council is 744,062.
