Changwon (Korean pronunciation: [tɕʰaŋ.wʌn]) is the capital city of Gyeongsangnam-do, on the southeast coast of South Korea. With a population of 1.07 million as of 2015, Changwon is South Korea's 9th most populous city. A port city, Changwon is bordered by Masan Bay to the south, and the cities of Busan and Gimhae to the east. The city of Miryang lies to the northeast, and Jinju to the west. The region has been inhabited since the Bronze Age, and its urban areas have been renamed and re-organized many times throughout history. In 1974, with the creation of the Changwon National Industrial Complex, the three historically interdependent cities of Masan, Jinhae, and Changwon began to undergo significant economic development, growing into an important industrial centre. On July 1, 2010, the cities of Changwon, Jinhae, and Masan merged to form the current city of Changwon. As Korea's first planned city, modeled after Canberra, Australia, Changwon uses accessible urban planning including a large number of parks and separate residential and industrial areas. The city has also branded itself an "environmental capital" with the municipal government actively participating in climate change conferences and committing to the development of sustainable policies like the globally recognized bike-sharing program, Nubija.
