Mr Suphachai nominated four other people: Boon Rawd executive Jutinan Bhirombhakdi, CAT Telecom CEO Kittisak Sriprasert, Google Thailand head Ariya Banomyong and True presenter Urassaya “Yaya” Sperbund.
If these four nominees take up the challenge, Mr Supachai would donate four more million baht to four charity foundations.
