Local authorities at Changshu in Jiangsu Province have ordered port operations stopped while they investigate the death of four workers while unloading cargo.

The stop work order has idled both Singaporean controlled Changshu Changjiang International Port (CCIP) where the fatalities occurred last weekend, and its sister port, the larger Changshu Xinghua Port Co (CXP).

The sister ports are upriver from Shanghai on the south bank of the Yangtze River opposite Nantong.
