Our strategic affiliation with Shandong Dongming Petrochem Holdings Group (“Dongming Petrochem”) began in 2006 when we acquired Dongming Hengchang, where Dongming Petrochem was one of the founding shareholders. Dongming Hengchang was originally set up in 2000 as a joint venture between Dongming Petrochem and its key management staff, in line with the PRC’s broad policy of reforming its state-owned enterprise, in particular, for the non-strategic downstream petrochemical activities. It was based on the premise of exclusive supply contracts with some of the companies within Dongming Petrochem Group to secure a stable and secure provision of its major new material – raw LPG. Since incorporation, Dongming Hengchang was able to introduce into an exclusive agreement with Dongming Petrochem and one of its associated societies to be supplied of all their raw LPG to Dongming Hengchang exclusively for a period of 20 years from 2006. This ensures consistent supply of raw LPG from various channels for Dongming Hengchang. On 31 May 2016, Dongming Hengchang entered into the 2016 Exclusive Supply Agreement with Dongming Zhongyou Fuel and Petrochemical Company Limited (a full subsidiary of Dongming Petrochem), for a term of 20 years from 2016. The 2016 Exclusive Supply Agreement supersedes the 2006 Exclusive Supply Agreement entered on 26 April 2006. We have gained largely from Dongming Hengchang’s history and affiliation with Dongming Petrochem. Dongming Petrochem, established in 1997, has since grown to become China’s largest independent oil refiner with primary processing capacity of 15 million tons per year. For Sinostar, through the strategic relationship with Dongming Petrochem, we are assured to receive a secure and stable supply of raw LPG which creates a solid foundation for us to continue ramping up on our existing market leadership position. The affiliation also ensures that the raw LPG we supply is of consistent quality and provide us with a competitive edge over our competitors.
