Prime Minister Yoshihide Suga plans to speak with U.S. President Donald Trump by phone on Sunday night, Japanese government sources said Friday, in what will be their first conversation since Suga took office.

Suga, leader of the Liberal Democratic Party, was elected Japan's first new prime minister in nearly eight years by the Diet on Wednesday to succeed his predecessor, Shinzo Abe, who had built one of the closest relationships with Trump among world leaders.

Suga has vowed to continue on the path set out by Abe, who resigned for health reasons, by keeping the security alliance with the United States as the cornerstone of Japan's foreign policy.
