Several Allied players have managed to break through in Burma and sweep Indochina with British/American armour. The problem is that everything bogs down in China because of the poor transportation network and poor supply flow. Until you win some Chinese ports on the South China Sea ops move slowly. And it is hard to bring ships in to the SCS when the Japanese control the air in the Sumatra, Malaya, Philippines, Borneo, and Taiwan areas.
So at some point the land-war advance has to have a naval war advance to support it. And naval ops need nearby bases at which to replenish and repair. So you are back to island or coast-hopping. A few players tried operating B-29s from western China, but supply limits their ops too.
