In quoting Research Director Sota Kato, Turkey’s Anadolu Agency notes that new Prime Minister Yoshihide Suga will face a challenge in working with other countries.

“Suga has no foreign policy experience,” Kato said, “so there is no knowing how effective he will be in international relations. It is hard to imagine Suga establishing the kind of personal rapport that Abe was able to build with other world leaders, notably [US President] Donald Trump.”
