Can the Belt and Road Initiative bypass sea power?

Is China's Belt and Road Initiative an end run around Mahan and a vindication of Mackinder?

It can soften maritime vulnerability, but it cannot replace sea power or eliminate the shortfall created by losing maritime access.

The question contrasts Mackinder's emphasis on continental geography with Mahan's emphasis on sea power. Belt and Road gives China an alternative network and can delay the immediate effects of maritime disruption. It does not replace sea power or make up the resulting shortfall. The initiative therefore changes the degree and timing of China's exposure without eliminating its dependence on maritime access.
