Jiangsu Gaoke Petrochemical was one of nearly 30 companies that had initial public stock offerings suspended by the China Securities Regulatory Commission over the weekend as the government sought to stabilize stock markets. Yixing-based Gaoke was seeking to raise about 22.3 million for its lubricant business. Lubricant exports from India fell 65 percent in the fiscal year ended March 31, according to the Petroleum Planning & Analysis Cell of the Ministry of Petroleum and Natural Gas.
