Asked if China’s manmade islands were a cause for concern, Rodrigo Duterte told CNN Philippines, "No, because if it really were a serious concern, the US should lead the way and stop it right in the beginning."
In July, an international tribunal in The Hague rejected China’s claims on disputed islands and rebuked its activity in the South China Sea, including the construction of artificial land.
Duterte said the only way to settle the territorial row with Beijing would be by enforcing the Hague court ruling legally or going to war with China.
The Philippines and China are both laying claims to the Spratly Islands in the South China Sea, which are also contested by Taiwan, Vietnam and Malaysia. The US Navy has maintained its presence in the region on allegations it wanted to uphold freedom of navigation.
