Taiwan, officially the Republic of China (ROC), is a highly developed island nation situated in East Asia, primarily located between the East and South China Seas. The main island, also known as Formosa, is geographically defined by the Taiwan Strait to the north and the Pacific Ocean to the east. Its strategic location, bordered by the People's Republic of China (PRC) to the northwest and Japan to the northeast, has historically made it a critical crossroads of global trade and culture. The country is characterized by a dense concentration of population in the western plains, contrasting sharply with the rugged, mountainous terrain that dominates the eastern two-thirds of the island. With a highly advanced economy and a robust democratic system, Taiwan is recognized globally for its technological prowess and vibrant society.
