Cosco Pacific, one of China's largest port operators, is exploring the possibility of taking an equity stake in Greek ports. Wei Jia Fu, chairman of Cosco Pacific, and Greek Prime Minister Kostas Karamanlis met in Beijing last month. 'We spoke about the possibility of investing in ports but they were just preliminary talks,' one senior manager said. Mr Wei said that he wanted to deepen Cosco Group's links on port investment, liner service, vessel chartering and crew manning services. Meanwhile, Cosco Group and Piraeus Port Authority will meet in Athens on Sunday for more talks on a possible acquisition, according to reports. The authority is 74.14 per cent owned by the Greek government, which administrates and operates ports in Greece. Cosco Pacific's shares rose 4.6 per cent yesterday to $15.80. The shares have gone up 8.2 per cent this year.
