Interesting to see this story covered in the international press because most of the local press (Bangkok Post, The Nation) have portrayed the rice subsidies as being a huge benefit to the farmers (which they are) and have not really addressed the fact that raising the world price encourages other nations to produce more rice in an effort to bring the price back down.
The Philippines, which was mentioned in the article, has done a lot to increase their rice production after the shortage a few years back. Expect a lot more countries to use Thailand's price increase to invest even more into becoming more self-sufficient.
Of course, if you took Economics 101, you see this for what it is. Thailand, an export economy, is mucking with their number one export and creating conditions which make it more profitable for other nations to compete with them. Hmmmm . . . . again, if you took Econ 101, you know this rarely ends well.
