SINGAPORE, July 24 (Reuters) - Asia's middle distillates markets turned slightly more upbeat, with trading sentiment firming slightly amid falling stockpiles in Singapore and as more physical window spot discussions emerge.

Talks of some August spot cargoes from northeast Asian refiners being done at discounts of 60-80 cents per barrel surfaced, though further details could not be confirmed.

More China-origin jet fuel offers also emerged in the spot market.

The east-west price spreads narrowed slightly from the previous trading session, with Asian markets strengthening slightly given a lack of swing supplies within this region in the near-term.

Refining margins GO10SGCKMc1 held steady at $21 a barrel at Asian market close.

On the trading window, deals for higher-sulphur gasoil cargoes resurfaced, but discussions for 10ppm sulphur gasoil remained muted. Cash differentials GO10-SIN-DIF edged up to $1.66 a barrel, reflecting the steeper paper market backwardation.

Regrade JETREG10SGMc1 widened slightly to discounts of around $2.4 a barrel.
