Thailand plans a yearly "supply wipe" of up to 50,000 tonnes of natural rubber output by reducing the country's rubber growing areas, to try to stimulate international prices, the Rubber Authority of Thailand told Reuters on Thursday.

The front-month rubber contract on Singapore's SICOM exchange for August delivery last traded at 132.5 US cents per kg, down 0.1 cent.
