Growth was mainly generated by increased demand for imports in developing regions, with container trade volumes expanding strongly on the non-mainlane East-West, North-South and intraregional lanes. Non-mainlane East-West trade grew by 8.9 percent, while North-South and intraregional trades expanded by 8.9 percent and 9.2 percent respectively. According to data from Clarkson Research Services, in 2011, the three mainlane trades totalled 47.3 million TEUs, while the non-mainlane trades reached 103.3 million TEUs.
