The role of PGN, which became Pertamina's gas subholding unit last year, so far has been focused on the gas utility business, Reuters reported. PT Pertamina is Indonesia's state-owned oil and gas company.
PGN earlier this month signed an agreement to sell LNG to China's Sinopec next year.
Putra said the trade business is currently in transition from Pertamina to PGN and the two companies are working together to manage international transactions.
PGN director Syahrial Mukhtar said last week that the company would seek more LNG buyers in China, including more transactions with Sinopec. PGN hopes to secure a deal by the end of the year with a Chinese buyer, he said without sharing further details, Reuters reported.
Pertamina and PGN are looking for buyers for LNG from Pertamina's Bontang plant to replace contracts that will expire next year, Mukhtar said.
