Weihai, a coastal city in Shandong, held a trade and investment promotion campaign in the World Trade Centre Club Hong Kong Wednesday for 109 projects with potential investment of $34.8 billion.

Contracts for as many as 18 projects were signed, with total investment of more than $990 million.

The projects mainly involve the high-end industry, the emerging industry and modern services.

"With more and more Hong Kong-backed projects coming to Weihai, cooperation between Hong Kong and Weihai has entered a new stage," said Wang Peiting, party chief of Weihai at the promotion campaign.

Wang said the coming five years will see Weihai focusing on aquatic products processing, ship-building, port logistics, coastal tourism, new energy and modern petrochemicals.

According to Weihai government figures, the city produced aquatic products weighing 2.13 million metric tons and built ships with total capacity of four million deadweight tons and had wind power installed capacity of 133,000 kilowatts last year.
