SINGAPORE: Malaysian palm oil futures edged lower on Wednesday, weighed down by weakness in rival oils and the country's move to raise export taxes for the commodity.

Malaysia Derivatives Exchange fell 2 ringgit, or 0.1%, to 3,409 ringgit ($839.24) in early trade. The contract gained 0.3% on Tuesday.

The weakness in palm oil was mainly due to cheaper rival oils elsewhere, a Kuala Lumpur-based trader told Reuters.

Soyoil on the Chicago Board of Trade was last down 0.1% after rallying overnight as a labour strike in Argentina entered its 13th day.

On the Dalian Commodity Exchange, soyoil fell 0.6% and palm oil declined 0.8%.

Palm oil is affected by price movements in related oils as they compete for a share in the global vegetable oils market.

Malaysia has raised its January export tax for crude palm oil to 8% from 6.5% in December, a circular on the Malaysian Palm Oil Board website showed on Tuesday.

Palm oil may retest a support at 3,381 ringgit per tonne, a break below which could cause a fall to 3,300 ringgit, Reuters analyst Wang Tao said.
