Qinhuangdao Port is a strategically important port and is the largest coal shipping port in the country, much of which is shipped to power plants elsewhere in China. With recent expansion, its capacity has reached 209 million metric tons. The harbor is adding a further six berths to add capacity and is increasingly being invested in by other port operators, such as South Africa's Port of Richards Bay, who have announced plans to invest US$150 million to increase capacity by at least 28 percent.
