March 18 (Reuters) - The mainstream spot quotation range for xylene in East China is 7,800–7,830 yuan/ton, up 25 yuan/ton from the previous trading day. Driven by high crude oil prices and strong gains in refined oil products, buying interest in the toluene and xylene markets has shown signs of recovery. Coupled with expectations of medium- to long-term production cuts at refineries, the persistently tight supply-demand balance continues to support prices. In the previous trading session, related product prices opened lower but rebounded within a narrow range. It is expected that the market will maintain firm and volatile pricing during the day, with sellers keeping their offers steady. Subsequent attention should focus on the pace of follow-up buying activity.
