SINGAPORE, June 26: Malaysian crude palm oil futures ended higher on Tuesday, supported by rising exports and concerns that drought in the United States could damage the soybean crop and limit global supplies of edible oils. But gains were limited in a choppy trading session as investors turned sceptical ahead of a summit of European leaders later this week that looks unlikely to take concrete measures.Benchmark September palm oil futures on the Bursa Malaysia Derivatives Exchange edged up 0.2 per cent to close at 3,035 ringgit ($951) per ton. Prices traded in a narrow range between 3,010 and 3,036 ringgit.Traded volumes were thin at 16,908 lots of 25 tons each, compared to the usual 25,000 lots.—Reuters
