Thailand, Indonesia and Malaysia, which together form the Tripartite Rubber Council (ITRC), had earlier this month said they would cut rubber exports by a total of 240,000 tonnes for four months from April under the so-called Agreed Export Tonnage Scheme (AETS), looking to boost flagging prices.

However, officials from Indonesia and Malaysia on Monday said Thailand would be delaying the start of its four months of cuts until May 20 due to the election that took place there the day before, its first since a 2014 coup.

They did not specify why the election was delaying the cuts, while Thailand was yet to officially confirm the move.

"According to an agreement at a senior official meeting, implementation (of AETS) by Indonesia and Malaysia will start on April 1, and Thailand will start on May 20," Kasan, head of the Trade Policy Analysis and Development Agency at Indonesia's trade ministry, told Reuters.

A source at Malaysia's primary industries ministry confirmed the information from Indonesia.

Indonesia's cuts are expected to account for 98,000 tonnes of the total. It is unclear how Thailand and Malaysia will divide the rest of the curbs.
