The visit of US President Barack Obama to Cambodia to attend two regional meetings on Nov. 19 showed he isn't the only boy on the block, pivot to Asia or no pivot to Asia. Obama and his vast traveling entourage were humiliated by the way the Cambodian strongman Hun Sen organized protocols. No welcome sign greeted Obama upon his arrival at Phnom Phenh Airport. Rather, the area was strewn with welcoming signs for visiting Chinese Premier Wen Jiabao.
