TOKYO: Japan's new Prime Minister Yoshihide Suga pledged Wednesday to keep coronavirus infections under control and kickstart an economy in recession, as Shinzo Abe left office after a record-breaking tenure.

In his first remarks after being elected by parliament earlier Wednesday, Suga emphasised his will be a cabinet of continuity, seeking to further the policies championed by Abe.

"We need to carry forward the policies that the Abe administration was pushing, I feel that is the mission for which I have been called," Suga told reporters.

He sidestepped questions on the possibility of a snap election to consolidate his position, saying that "what the public wants right now is that we manage to end the pandemic soon and at the same time we steadily restore the economy".

"Achieving both the prevention of the spread of infection and rebuilding the economy is what they desire most... We hope to do our best on this issue first."

He dwelled little on political ideology or foreign policy goals, instead pledging administrative reform, an end to "bureaucratic silos", and greater digitalisation of government.

He said he would seek continued strong ties with Washington and stable relations with China and Russia.

But he offered no details and made no mention of ongoing tensions with South Korea, or any specifics of his defence strategy, particularly towards North Korea.

The 71-year-old takes the top job after decades in politics, most recently in the role of chief cabinet secretary, where he was a key enforcer of government policy as well as spokesman.
