Hanoi - Vietnam waived an export tax on rice and ordered the state rice cartel to boost purchases in an effort to raise sales abroad and reduce a surplus that has hurt farmers' incomes, officials said Friday.

A decree issued Thursday by Prime Minister Nguyen Tan Dung orders Vietnam's state-owned food companies, which control the country's rice exports, to buy between 400 and 500 thousand tons of rice in August, and "to make sure that farmers make profits of 40 per cent or more."

Singapore - Soaring prices for agricultural commodities are whetting investors' appetites for agri-funds that have been sprouting in Singapore, news reports said on Monday.
