Is Russia about to do a favor for Thailand's PM?

Apparently Thai PM Samak just made a deal to buy diesel from Russia at an astoundingly low price:

Manoon Siriwan, an energy expert and former deputy managing director of Bangchak Petroleum, agreed that eight baht a liter cheaper seemed too good to be true.

Maybe Samak is an awesome negotiator. But I can't help but wonder what Thailand might have offered Russia in exchange for such a steep discount. What does Bangkok have that Moscow badly wants -- aside from Victor Boot?*
