March 16 (Reuters) - The mainstream spot quotation range for xylene in East China is 7,600-7,800 yuan/ton. In the previous trading day, toluene and xylene showed a slight upward trend. Overnight, international crude oil prices rose, coupled with the increase in aromatics during the night session, which improved sentiment in the spot market. However, downstream buyers and traders remain cautious, showing weak willingness to chase higher prices, and further upward movement faces significant resistance. It is expected that the market will mainly experience high-level volatility today.
