Sea, road, and river supply routes into China

The proposed China campaign depends first on the Royal Navy maintaining a sea line of communication for troops and supplies. An existing road or railway project from India into China could then be accelerated. The Yangtze, Pearl, and Yellow rivers could carry ocean-going shipping far inland, while existing river gunboats provide a starting point for local control. That access contrasts with the D-Day problem of sustaining an army across open beaches without immediately captured ports. Inadequate roads and patchy railways would still limit the final movement of supplies, so water transport reduces the inland logistics problem without removing it.
