Orient Overseas (International), the shipping giant controlled by Hong Kong Chief Executive Tung Chee-hwa's family, said two of its subsidiaries have entered into a contract with Samsung Heavy Industries Co Ltd to build two container vessels. The two post-Panamax container vessels, worth a total of $160 million, represent about 20.9 percent of OOIL's net tangible assets, the company said in a published statement. Each can carry 7,400 teu. OOIL said the new vessels, to be funded by internal resources and external finance, will improve the operating efficiency and profitability of the group. - (Reuters)
