Thai-Sino relationship is better than Singapore-Sino's.

Singapore always wants to extol the strong Singapore-Sino relationship but the real truth is Thailand got invited to the BRICS summit.  Thailand is not part of BRICS but is the only ASEAN country to get invited to attend BRICS.

Being able to attend BRICS means there'll be an abundance of business and trade opportunities to harness with the 2 largest population countries.  Therefore, attending the BRICS summit is better than attending the G20 summit as an observer.

Singapore! Wake up please!
