No, it would still be true. Just beyond Taiwan on the north side are the furthest islands in the Japanese island chain, and if you instead head south, you see Philippine islands instead. Head through the South China Sea and you end up either having to run past Singapore through the Straits of Malacca (already a critical, congested chokepoint), or travel through the internal waters of Indonesia or the Philippines (admittedly, I'm not sure you could call Singapore, Malaysia, or Indonesia US allies, given the general ASEAN propensity for neutrality).
