The Prime Minister of Thailand has revived the idea of an OPEC-style Southeast Asia rice cartel.

However, analysts said the plan will not work due to the inability of governments to co-operate with each other and control output from their farmers.

The proposal by Samak Sundaravej the Thai PM, who also happens to be a TV chef, threatens to add to global food supply fears amid record high rice prices.

But it failed to gain traction seven years ago when it was first floated by Bangkok and most see little chance it will fare better this time around.

The five mainland Southeast Asian nations produce a combined 60 million tonnes of milled rice each year, about 14% of world output.

But only Thailand, the world's number one rice exporter, and Vietnam have major surpluses, last year accounting for about 47% of world wheat trade.

Mr Samak held talks with visiting Burmese Prime Minister Thein Sein and afterwards said they had agreed in principle to the idea.

Burma has resumed limited rice exports this year, mainly to South Asia, after several years off the market.

The proposed group, which includes two democracies, two Communist-led governments and a military dictatorship, appears in no hurry to hammer out the details.

Agriculture ministers will discuss the proposal in September at a meeting of the 10-nation ASEAN regional group in Vietnam.
