2011 China was not a 'poor country', even in GDP per capita nominal which was higher than most ASEAN members except Singapore and Malaysia. At worst, it was moderate. In terms of actual outcomes like literacy, lifespan, patents, fortune 500 companies, etc China already had indicators that at minimum were comparable or better than countries with even double the nominal GDP per capita at the time like Mexico and Turkey (which have since been overtaken) and at maximum were world leading.
Thailand with similar GDP per capita in 2011 did not have SMIC, Huawei, Tencent, Alibaba or any cultural influence outside Thailand.
