Next World Collider will be built in China. They are about the only major country increasing government R&D funds. The only exception would be if there is a breakthrough technology 100x more cost effective, i.e. you could build a 10x power LHC for a tenth of the cost. I see press releases of breakthroughs using lasers or EMF. But very unclear if they'd scale up to a petavolt. Probably could build a pretty powerful accelerator using the world's electricity devoted to bitcoin mining :-)
