China's manufacturing economy depends on importing raw materials and exporting finished goods through maritime trade. The Belt and Road projects discussed here include roads and railways that offer an alternative route toward Europe. Their carrying capacity is only a small insurance policy beside the volume that sea lines of communication can move. Dependence on those sea routes helps explain why naval investment rose with China's integration into the global economy.
