HAVANA (AP) — Fifty-seven-year-old Communist Party official Miguel Mario Diaz-Canel Bermudez replaced Raul Castro as the president of Cuba on Thursday, pledging to preserve the island’s communist system while gradually reforming the economy and making the government more responsive to the people.

Addressing the nation live on television, Diaz-Canel said Castro, 86, would remain the country’s ultimate authority as head of the Communist Party. Castro’s 12 years as president ended shortly after 9 a.m. when the head of the country’s electoral commission announced that all but one of the 604 members of the National Assembly had approved Diaz-Canel as sole candidate.

The two men climbed the dais before the assembly. Diaz-Canel and Castro embraced, and Castro left the stage.

“The people have given this assembly the mandate to provide continuity to the Cuban Revolution during a crucial, historic moment that will be defined by all that we achieve in the advance of the modernization of our social and economic model,” Diaz-Canel said.

He said Cuba was, as always, prepared to negotiate with the United States but unwilling to cede to any of Washington’s demands for internal change.

He emphasized that reforms would follow a 12-year-plan laid out by the National Assembly and Communist Party that would allow moderate growth of private enterprise while maintaining the important sectors of the economy in the hands of the state.

With Castro watching from the audience, Diaz-Canel made clear that he would defer to the man who, along with his brother Fidel, founded and ruled for six decades what has become of one of the world’s last communist governments.

“I confirm to this assembly that Raul Castro, as first secretary of the Communist Party, will lead the decisions about the future of the country,” Diaz-Canel said. “Cuba needs him, providing ideas and proposals for the revolutionary cause, orienting and alerting us about any error or deficiency, teaching us, and always ready to confront imperialism.”

Facing biological reality but still active and apparently healthy, Raul Castro is stepping down as president in an effort to guarantee that new leaders can maintain the government’s grip on power in the face of economic stagnation, an aging population and increasing disenchantment among younger generations.

Diaz-Canel’s half-hour speech offered most Cubans by far their greatest exposure to the man long expected to assume the presidency.

Most Cubans know their first vice president as an uncharismatic figure who until recently maintained a public profile so low it was virtually nonexistent. That image changed slightly this year as state media placed an increasing spotlight on Diaz-Canel’s public appearances, including remarks to the press last month that included his promise to make Cuba’s government more responsive to its people, language he echoed on Thursday.

Diaz-Canel gained prominence in central Villa Clara province as the top Communist Party official, a post equivalent to governor. People there describe him as a hard-working, modest-living technocrat dedicated to improving public services. He became higher education minister in 2009 before moving into the vice presidency.

In a video of a Communist Party meeting that inexplicably leaked to the public last year, Diaz-Canel expressed a series of orthodox positions that included somberly pledging to shutter some independent media and labeling some European embassies as outposts of foreign subversion.

But he has also defended academics and bloggers who became targets of hardliners, leading some to describe him a potential advocate for greater openness in a system intolerant of virtually any criticism or dissent. International observers and Cubans alike will be scrutinizing every move he makes after he officially takes office on Thursday.

Two years after taking over from his ailing brother in 2006, Castro launched a series of reforms that expanded Cuba’s private sector to nearly 600,000 people and allowed citizens greater freedom to travel and access to information. He has failed to fix the generally unproductive and highly subsidized state-run businesses that, along with a Soviet-model bureaucracy, employ three of every four Cubans. State salaries average $30 a month, leaving workers struggling to feed their families, and often dependent on corruption or remittances from relatives overseas.

Castro’s moves to open the economy have largely been frozen or reversed as soon as they began to generate conspicuous shows of wealth by the new entrepreneurial class in a country officially dedicated to equality among its citizens.

As in Cuba’s legislative elections, all of the leaders selected Wednesday were picked by a government-appointed commission. Ballots offer only the option of approval or disapproval and candidates generally receive more than 95 percent of the votes in their favor.

The Candidacy Commission also nominated another six vice presidents of the Council of State, Cuba’s highest government body. Only one, 85-year-old Ramiro Valdez, was among the revolutionaries who fought with the Castros in the late 1950s in the eastern Sierra Maestra mountains.

State media went into overdrive Wednesday with a single message: Cuba’s system is continuing in the face of change. Commentators on state television and online offered lengthy explanations of why Cuba’s single-party politics and socialist economy are superior to multi-party democracy and free markets, and assured Cubans that no fundamental changes were occurring, despite some new faces at the top.
