“The chance of inflicting hurt to aviation actions or (on individuals and actions) on the bottom is extraordinarily low,” overseas ministry spokesman Wang Wenbin stated Friday.

Beijing has poured billions of {dollars} into area exploration to spice up its world stature and technological would possibly.
