Denpasar-Prime Minister Yingluck Shinawatra of Thailand said that many private companies are increasingly interested in investing in Indonesia. Yingluck statement on the ASEAN Summit in Bali last week, it is not merely limited to large-scale business, but also medium-sized businesses.

For example, Earth Energy Plc, an importer and distributor of medium-scale coal from Thailand,intends to buy coal Kalimantan for the Thai market. But they did not know there's lots of coal rogue brokers. Handyman deception was successful thrash Earth Energy Plc for 10 million baht (Rp3 billion). Earth Energy's definitely dizzy, but instead learn to be more careful.

After holding a local partner who can be trusted, even change the course of Earth Energy's business. Than a coal merchant, became the owner of the coal fields more reliable to supply the needs of the Thai market.

Early last month, the Earth took over the shares of PT Tri Tunggal Patriat the have the coal mining business license in South Kalimantan in the scheme of exchange of shares (share-swap) worth one billion baht (300 billion).

"If you want a business in Indonesia must know the culture and who your partner," said Managing Director of PT Tri Tunggal Patriati Khajohnpong Khamdee, whose family founded the Perfect Energy four years ago in Thailand. Energy Prefect is taking over other companies listed on the Stock Exchange of Thailand and then diubanh into Earth Energy.

Khajohnpong know there are two major companies in the Stock Exchange of Thailand has a coal mining concession in Indonesia, Banpu and PTT. But not for their Earth Energy. Because it takes another approach to business.

Khajohnpong have good relations in Thailand and Indonesia. He took five new shareholders in the Earth, including Sri Nugoo-ins that his group took over the shares of PT Tri Tunggal Patriati last year.

Khajohnpong is a former top executive at the National Power Supply (from Advance Agro business groups) that buy coal Indonesia since 2007. He was fluent in Indonesian. He therefore close to the Borneo Post newspaper owner who became a director at PT Tri Tunggal.

PT Tri Tunggal had two coal mines in South Kalimantan with deposit 7.4 million tonnes. The company has held the contract to supply two million tonnes of coal by Chinese companies in the next four years.

Mine in Sebamban have a deposit of 2 million tons of production early last Friday, and will be sent to China as much as 60.00 tonnes in the fourth quarter of this year. Acquisition of PT Tri Tunggal makes Earth Energy as the third largest coal miner in the Exchange of Thailand after Banpu and Lanna resourses.

For Khajohnpong, the transformation of merchant into the coal miners is an important step to avoid the risk of rising coal prices. "This move is not without risk. The reality is the opportunity to grow the business, because Indonesia has a far more coal than Thailand, "he said with a smile
