Indonesian Coordinating Minister for Economy Hatta Rajasa said on Friday that the country had extended operation period at four main sea ports following the implementation of the ASEAN-China free trade on Jan. 1. More imports have been predicted to flow in Indonesia which has huge domestic market with over 230 million people, but, with soaring global demands and prices of exports from emerging markets, it is predicted that the country's exports would rise. 'The operation period has risen to 24 hours a day, seven days a week, in the four main sea ports. It is at sea ports of Tanjung Priok (Jakarta), Tanjung Perak (East Java), Belawan (North Sumatra) and Makassar sea ports (South Sulawesi), Rajasa said at his speech at Tanjung Priok sea port here. Indonesia has started to recover from the fallout of the global recession with its exports forecast to grow at about 5 percent this year after a decline of 17-19 percent last year, Trade Minister Mari Elka Pangestu has said.
