This strategic partnership between PETRONAS and METLEN marks a significant step toward strengthening the relationship between the two companies and lays the foundation for new opportunities for collaboration.

METLEN's Chief Executive Director International Energy Supply & Trading, Panayotis Kanellopoulos, said: "This agreement with PETRONAS represents an important step in strengthening METLEN's strategy to diversify its LNG sourcing. By expanding our international synergies, as with this leading global LNG player, we further enhance flexibility and reliability of supply, supporting both our customers and the broader regional market, as well as Greece's energy hub credentials."

PETRONAS Executive Vice President and CEO of Gas & Maritime Business, Datuk Adif Zulkifli said, "This agreement with METLEN underscores PETRONAS' commitment to delivering reliable and flexible LNG solutions that support our customers' evolving energy needs.
