Maintaining an import-dependent economy might be a factor, economies are complicated. But there isn't a fundamental reason that taking in more stuff than gets exported should mean that Asia has to be more successful. If anything, a country in a position to import more than it exports should be seeing big jumps in living standards, rather the gains going to a country notionally taking the bad end of the bargain. And there are some easy resolutions to being a net importer and while having a strong industrial economy - import raw materials, make stuff that isn't for export as an example.
