Reuters reported on Wednesday that, according to sources, PTT’s retail unit was planning to participate in first-round bids due by Jan. 15 for the assets worth up to $9 billion (£6.9 billion).
Thailand’s largest retailer, Central Group, and agribusiness conglomerate Charoen Pokphand (CP) Group are also set to take part, the sources said.
A spokesman for PTT declined to comment further.
Tesco, which has 1,967 stores in Thailand and 74 in Malaysia, said last month that it had begun a review of its Asian operations after receiving approaches for the businesses.
