HANOI: Vietnamese rice export prices rose this week on prospects of a new order from the Philippines, while weaker demand pushed down rates of the Thai variety for a seventh straight week.

Vietnam's 5% broken rice prices rose to $485-$490 per tonne versus last week's $470.

"Domestic rice prices have risen recently as traders are buying in anticipation of a move by the Philippines government to buy 300,000 tonnes soon," a trader based in Ho Chi Minh City said.

However, weaker demand kept trading relatively muted this week, another trader said.

The country's rice exports in September fell 36.4% from the previous month to 385,429 tonnes, government data showed.
