Tokyo Commodity Exchange (TOCOM) futures, which set the tone for rubber prices in Southeast Asia, jumped on expectations of curbs on exports from major producers and a trade deal between China and the United States. The benchmark Tokyo Commodity Exchange (TOCOM) rubber contract for July delivery finished 6.2 yen ($0.0560) higher at 199.8 yen per kg.

The most-active rubber contract on the Shanghai futures exchange for May delivery rose 40 yuan ($5.97) to finish at 12,445 yuan per tonne. TOCOM's technically specified rubber (TSR) 20 futures contract for August delivery closed up 5.7 yen at 170.2 yen per kg. The front-month rubber contract on Singapore's SICOM exchange for March delivery last traded at 144.8 US cents per kg, up 0.1 percent.

The world's top producers of natural rubber said on Friday they would curb exports by up to 300,000 tonnes in a bid to prop up global prices for the commodity.
