"Demand is stable. Rice transportation and loading operations at a few ports were disrupted earlier this week due to the cyclone," said an exporter based at Kakinada in the southern state of Andhra Pradesh.

In Thailand, prices for five per cent broken rice rose to $457-$485 per tonne from $454-$475 a week ago driven by higher container freight charges, while overseas demand remained subdued.

However, some traders said an expected arrival of more supply could help ease prices.

Vietnamese five per cent broken rice stayed unchanged for the third week at $490-$495 a tonne.

"Supplies are low, while some exporters are hesitant to sign new contracts due to the problems of container scarcity, especially for shipments to Europe and the Middle East," a trader based in Ho Chi Minh City said.

Vietnam was, however, seeing an uptick in demand especially from China and the Philippines, which recently cut its import tariff on rice, a trader said.
