Tevin Vongvanich, 58, has presided over the country's biggest oil company during a period when global crude prices fell into the doldrums. "When I was around 14 years old, I worked at a petrol station," Mr Tevin says. Some 40 years ago, Mr Tevin was a part-time worker at a petrol station. Being PTT's president and chief executive, he must take care of several of the group's businesses, including oil, gas, power, petrochemicals and pipelines. "If executing an investment idea proves to be beyond our powers, we will stop it or otherwise rethink it," Mr Tevin says.
