The world can expect more geopolitical conflicts that will also impact Japan if Western powers fail to tackle global issues such as the Syrian refugee crisis and the rise of terrorism, according to leading political risk analyst Ian Bremmer.

"I think the real worry about the geopolitical environment is that we are setting in motion a world that is much more fragmented, a world where conflicts will grow and no one will respond to it effectively," Bremmer, who heads research and consulting firm the Eurasia Group, told The Japan Times during the World Economic Forum meeting in Davos, Switzerland, last week.

"I believe we are in this 'G-zero world,' so we are going to see much more geopolitical conflict," said Bremmer, who coined the word "G-zero world," which refers to a vacuum of power in international politics due to a decline in Western powers the G-7 and G-20.
