SINGAPORE, April 24 (Reuters) - Asia's middle distillates markets stayed upbeat, with more May offers emerging from China's refiners and cash differentials staying strong at three-month highs.

On the window, buying interest stayed upbeat though a lack of deals on a free-on-board Singapore basis was still evident like the previous trading sessions.

Cash differentials GO10-SIN-DIF continued to stay firm at three-month highs of around 70 cents per barrel amid a lack of lower-priced offers.

Refining margins GO10SGCKMc1 rebounded back to nearly a two-week high of $14.4 a barrel, as front-month market performance stayed robust amid bullish near-term outlooks from the supply front.

India exports for April are likely to be low at slightly more than 1 million metric tons, LSEG and Kpler shiptracking data showed.

For jet fuel, the arbitrage between Asia and the U.S. West Coast narrowed significantly through the course of the week and enquiries turned thin.

Spot deals in the past few trading sessions remained at discounts of 80 cents to $1 per barrel, with at least two cargoes being sold at such levels this week.

Regrade JETREG10SGMc1 however narrowed to 75 cents per barrel, with front-month jet fuel markets still firming up.
