KUALA LUMPUR: Malaysian palm oil futures extended gains for a second consecutive session on Tuesday, buoyed by stronger rival Dalian oils and firmer export data, though weaker Chicago soyoil and crude oil prices capped the rise. The benchmark palm oil contract for March delivery on the Bursa Malaysia Derivatives Exchange gained 17 ringgit, or 0.43%, to 4,002 ringgit ($984.26) a metric ton in early trade.
