KUALA LUMPUR, Sept 22 (Reuters) - Malaysian palm oil futures extended losses to a second session on Tuesday as Dalian prices weakened, but hopes of strong demand ahead of key festivals in China and India capped losses.

The benchmark palm oil contract for December delivery on the Bursa Malaysia Derivatives Exchange slid 27 ringgit, or 0.9%, to 2,980 ringgit ($721.03) a tonne by 0235 GMT. It had snapped a four-session rally to fall 2.4% on Monday.

Exports from Malaysia to the world's second-largest palm buyer China have picked up ahead of the week-long holiday for the Mid-Autumn festival, starting Oct. 1, according to cargo surveyor data.

Shipments are expected to be steady until next month, with arrivals to top buyer India expected to improve ahead of the Diwali festival there, according to Refinitiv Commodities Research. FUNDAMENTALS
