Oei Tiong Ham died in Singapore in 1924. In his will, he named nine children as heirs, one of whom was
Oei Tjong Hauw, whom he appointed to lead Kian-gwan Kongsi. Under Tjong Hauw, OTHC continue to expand, opening a rubber processing plant in Sumatra and an alcohol
distillery in Shanghai. Tjong Hauw also led the company to Japan and Indonesia - in this period many assets such as factories were destroyed during
World War II. Tjong Hauw died suddenly in 1950. After Tjong Hauw died,
Oei Tjong Tjay led OTHC. He was the youngest son of Oei Tiong Ham and Oei Ing Swie, son of Oei Tjong Hauw. Tjong Tjay, who was 27 at the time, found it difficult to adapt to the business climate in Indonesia, since he was raised abroad and lacked fluency in
Indonesian language. Indonesia's uncertain political conditions at the time also made it difficult to expand OTHC; many considered OTHC to be pro-Dutch due to its close relation with the Dutch during the independence war. Notwithstanding, in this period OTHC established many joint venture with local and governmental figures, such as
pharmaceutical company, Phapros which was established in 1954. Tjong chose to support the
PSI and
PNI party, but it the choice would become problematic when PSI figures were arrested and exiled abroad. Dispute with the
Indonesian government, which begins with the prosecution against
Bank Indonesia in
Amsterdam on OTHC disbursement breakdown in the bank, worsened relations toward the government. In July 1961, the Indonesian government decided to seize the entire assets of OTHC in Indonesia, and in 1964 the state-owned company Rajawali Nusantara Indonesia (RNI) was formed to manage these assets. This incident led to the end of OTHC in Indonesia, although Kian Gwan branches abroad survive under the sons of Oei Tiong Ham. One of the largest overseas branches is Kian Gwan Thailand, led by Oei Tjong Bo (the elder brother of Oei Tjong Tjay) that continues to this day in the field of property and electronic tools distributor. ==References==
