SINGAPORE, Jan 27 (Reuters) - Asia's middle distillates markets were overall weaker, reflecting the declines in swap discussions and the open trading window, even as February sales activity continued from various refiners.

February refiner sale discussions were still hovering in the discounted territory, with the latest South Korea-origin barrels being sold at discounts of 80-90 cents per barrel.

Likewise for jet fuel, February sales were mostly done at discounts of more than 50 cents a barrel.

Meanwhile, swing suppliers in India and the Middle East started off their February spot sale tenders, as KPC, Nayara Energy and MRPL emerged from the sidelines.

Refining margins GO10SGCKMc1 kickstarted the short working week lower, hovering again at three-month lows given as weakness for February swaps prices continued.

Complex refining margins however recovered to two-week highs of more than $2 per barrel, reflecting the weakness in crude prices in comparison.

Cash differentials GO10-SIN-DIF closed the trading session at 72 cents a barrel, as selling interest rose for early February cargoes.

Regrade JETREG10SGMc1 discounts went to their narrowest in one month, reflecting the weakness in gasoil markets.
