Japan’s parliament voted into law on Saturday a defence policy shift that could let troops fight overseas for the first time since 1945, amid Prime Minister Shinzo Abe’s push to loosen the limits of the pacifist constitution on the military.

Abe says the shift, the biggest change in Japan’s defence policy since the creation of its post-war military in 1954, is vital to meet new challenges such as from a rising China.

But the legislation has triggered massive protests from ordinary citizens and others who say it violates the pacifist constitution and could ensnare Japan in U.S.-led conflicts after 70 years of post-war peace. Abe’s ratings have also taken a hit.

The legislation “is necessary to protect the people’s lives and peaceful way of living and is for the purpose of preventing wars,” Abe told reporters after the bills were approved by the upper house. “I want to keep explaining the laws tenaciously and courteously.”

Japan’s ally the United States has welcomed the changes but China, where bitter memories of Japan’s wartime aggression run deep, has repeatedly expressed concern about the legislation.

“Recently we have noticed that voices in Japan opposing the bill have become louder by the day,” Chinese foreign ministry spokesman Hong Lei told a regular news briefing on Friday.

“We demand that Japan earnestly listen to these just voices domestically and internationally, learn the lessons of history, uphold the path of peaceful development, speak and act cautiously in security and military matters and take actual steps to maintain regional peace and stability,” Hong added.

The bills, already approved by parliament’s lower house, were voted into law by the upper chamber in the early hours of Saturday despite opposition parties’ efforts to block a vote by submitting censure motions and a no-confidence motion against Abe’s cabinet in the lower house. All were defeated.

A key feature of the laws is an end to a long-standing ban on exercising the right of collective self-defence, or defending the United States or another friendly country that comes under attack, in cases where Japan faces a “threat to its survival”.
