Da Nang is the fifth largest city in Vietnam after Ho Chi Minh City, Hanoi, Haiphong and Can Tho in terms of urbanization and economy. Located on the coast of the South China Sea at the mouth of the Han River, it is one of Vietnam's most important port cities. As one of the country's five direct-controlled municipalities, it is under the direct administration of the central government.

Da Nang is the commercial and educational centre of Central Vietnam, as well as being the largest city in the region. In addition to its well-sheltered, easily accessible port, Da Nang's location on the path of National Route 1A and the North–South Railway makes it a hub for transportation. It is located within 100 km (62 mi) of several UNESCO World Heritage Sites, including the Imperial City of Hue, the Old Town of Hoi An, and the My Son ruins. The city was previously known as Cửa Hàn during early Đại Việt settlement, and as Tourane (or Turon) during French colonial rule. Before 1997, the city was part of Quang Nam-Da Nang Province.

On 1 January 1997, Da Nang was separated from Quảng Nam Province to become one of four independent (centrally controlled) municipalities in Vietnam. Da Nang is listed as a first class city, and has a higher urbanization ratio than any of Vietnam's other provinces or centrally governed cities.

Kota Kinabalu , formerly known as Jesselton, is the state capital of Sabah, Malaysia and the capital of the Kota Kinabalu District. It is also the capital of the West Coast Division of Sabah. The city is located on the northwest coast of Borneo facing the South China Sea. The Tunku Abdul Rahman National Park lies to its west and Mount Kinabalu, which gave the city its name, is located to its east. Kota Kinabalu has a population of 452,058 according to the 2010 census; when the adjacent Penampang and Putatan districts are included, the metro area has a combined population of 628,725.

In the 15th century, the area of Kota Kinabalu was under the influence of Bruneian Empire. In the 19th century, the British North Borneo Company (BNBC) first set up a settlement near the Gaya Island. However, it was destroyed by fire in 1897 by a local leader named Mat Salleh. In July 1899, the place located opposite to the Gaya Island was identified as a suitable place for settlements. Development in the area was started soon after that; and the place was named "Api-api" before it was renamed after the vice-chairman of BNBC as "Jesselton". Jesselton became a major trading port in the area, and was connected to the North Borneo Railway. Jesselton was largely destroyed during World War II. The Japanese occupation of Jesselton provoked several local uprisings notably the Jesselton Revolt but they were eventually defeated by the Japanese. After the war, BNBC was unable to finance the high cost of reconstructions and the place was ceded to the British Crown Colony. The British Crown declared Jesselton as the new capital of North Borneo in 1946 and started to rebuild the town. After the formation of Malaysia, North Borneo was renamed as Sabah. In 1967, Jesselton was renamed as Kota Kinabalu, Kota being the Malay word for Fort and Kinabalu after the nearby Mount Kinabalu. Kota Kinabalu was granted city status in 2000.

Kota Kinabalu is often known as KK both in Malaysia and internationally. It is a major tourist destination and a popular gateway for travellers visiting Sabah and Borneo. Kinabalu Park is located about 90 kilometres from the city and there are many other tourist attractions in and around the city. Kota Kinabalu is also one of the major industrial and commercial centres of East Malaysia. These two factors combine to make Kota Kinabalu one of the fastest growing cities in Malaysia.
