Eka Tjipta Widjaja (; –2019, born in Quanzhou, China as Oei Ėk-Tjhong (), was a Chinese-Indonesian business magnate who founded the Sinar Mas Group, one of the largest conglomerates in Indonesia. After immigrating to Indonesia with his family when he was a child, Widjaja became a member of the PCC, traded copra in the mid 1950s, moved into the palm oil industry soon after, started a paper factory in the 1970s, and then entered financial services in the 1980s. At the time of his death, Sinar Mas had interests in paper, real estate, financial services, agribusiness, and telecom with holdings primarily in Indonesia, Singapore, Malaysia, and China, and Widjaja was listed by Forbes as the third-richest person in Indonesia with a net worth of approximately US$8.6 billion. Early life Widjaja was born Oei Ek Tjhong in Quanzhou, Fujian, Republic of China. He was the son of a Sulawesi (Celebes)-based trader. In around 1930, he and his mother moved to Indonesia (then the Dutch East Indies) to join his father who had already settled in Makassar, and he started helping his father to run a small shop. He was educated in a local Chinese school, but left at the age of fifteen to work as a hawker. As a teenager, he sold biscuits and candy from his bicycle. Career In his early career, Widjaja did various business, including trading cooking oil and agricultural products, coffee shop, pig rearing, bakery, and grave construction. During Japanese occupation, price controls devastated his cooking oil business. When Indonesia's war for independence against the Dutch crushed his commodity-trading business in 1949, he sold family jewelry to repay creditors and traded in his car for a bicycle. In the 1950s, when Indonesian military sent troops to Makassar to fight Andi Aziz in the Makassar Uprising and later Abdul Kahar Muzakkar in the Darul Islam Rebellion, Widjaja sold food and other supplies to the troops, forging ties between him and the military. He used the military ship to trade copra—the raw material to make coconut oil—from Manado to Makassar. And thus, his copra business started, later reaching Jakarta and Surabaya. However, the Permesta rebellion happened in Sulawesi and Widjaja decided to move to Surabaya. In 1962, CV Sinar Mas was first registered in Surabaya, and soon it opened a branch office in Jakarta. This company exported natural products and imported textiles. In 1968, Widjaja opened a cooking oil
