As PTT's plans to invest in power plants in the region involves mainly coal-fired plants, it has to look for opportunities to invest in coal mines as well, Chitrapong said.
Natthachart Charuchinda, executive vice president, said the company has investments in two coal mines in Indonesia, and is negotiating with additional mines near the existing ones. However, many players are attempting to acquire the same mines, so it is difficult to win the deals, he said.
"It is taking longer than expected to finalise the deals," he said.
Natthachart said earlier that PTT aimed to conclude two or three coal mine deals this year.
