Senior Associate

Jin specialises in energy (including power, LNG and renewables) and infrastructure M&A / projects in the Asia-Pacific region. 



Jin focuses his practice on the energy and infrastructure sectors and has worked on a number of transactions in those sectors in the Asia-Pacific region. He has experience working on matters in upstream and downstream oil and gas, power (both conventional and renewable), infrastructure and project joint ventures and development, and LNG. He also has some contentious experience of shareholder and energy disputes, including in relation to LNG and power corporate documents.

Jin's wide-ranging experience across a variety of sectors and involvement in the full lifespan of a deal, from due diligence to dispute, enables him to provide relevant and comprehensive advice that takes into consideration the wider aspects of a transaction. He also understands the needs of in-house teams from his experience on secondment to a FTSE 250 energy company in London and a virtual secondment to the downstream team of an international energy company in Singapore.

Jin's experience includes advising:

  • the Kansai Electric Power Company on its strategic alliance with Medco Power Indonesia in relation to a portfolio of thermal power plants (both operational and in development) in Indonesia 
  • a Southeast Asian pension fund on its joint venture investment and shareholder arrangements in a solar power portfolio in the UK
  • a number of international and regional clients, including Woodside, Chevron and Santos, on proposed acquisitions / disposals of upstream oil and gas interests in a number of jurisdictions including Malaysia, Myanmar, Indonesia, Bangladesh and Vietnam
  • a number of international and regional clients, including international oil and gas trading companies and Asian national oil companies, on proposed joint venture arrangements in the downstream sector in Southeast Asia
  • the Japanese consortium on its bid for the multi-billion dollar Kuala Lumpur (Malaysia) to Singapore High Speed Rail project
  • Beibu on its joint venture investment in the Muara Port in Brunei




Jin trained at the London headquarters of a leading international firm and has been based in Singapore since 2014. Prior to joining Herbert Smith Freehills at the start of 2018, he worked at the Singapore office of a US law firm.
