That 70% figure for Indians is likely due to resume fraud. The east and southeast Asian countries listed have much better educational systems than India.
Keep in mind that first-generation south Asians English skills are likely far better than first-generation east and southeast Asians. Sometimes this spills over even to the second generation, because children whose parents have impeccable English skills are better able to relate to 'American' culture than children whose parents have poor English skills. I would be curious to see the difference between Taiwanese and mainland Chinese.
