NEW DELHI (AP) -- The palm-flecked island nation of Sri Lanka plays host this week to leaders from dozens of Commonwealth nations at a summit it hopes will generate enough good will and photo opportunities to eclipse three decades of grim history -- massive civilian deaths, persistent media harassment and gangster-style politics.
Instead, as Friday's opening approaches, global focus remains trained on the country's 27-year civil war and alleged atrocities committed by both rebels and soldiers who, despite a sustained international outcry, have been spared from investigations and prosecutions since the war ended in 2009.
The leaders of Canada and India are boycotting the summit. Others have had to justify their plans to attend by promising to bring Sri Lanka's government to task. Queen Elizabeth II, who is 87, is not going, but her son, Prince Charles, is presiding over the meeting.
"It's a shame the Commonwealth has come to this," said former Caribbean diplomat Sir Ronald Sanders, now part of a Commonwealth panel charged with recommending reforms in the organization. Choosing Sri Lanka as a summit venue, which gives it the Commonwealth chairmanship for two years, "suggests we are not serious about Commonwealth values."
Sri Lanka denies any rights abuses were committed by its forces. It balks at demands for an independent investigation, with the country's president defending Sri Lanka's actions in comments to reporters Thursday.
"We are open. We have nothing to hide," Mahinda Rajapaksa said.
"We have our legal system in Sri Lanka," as well as a human rights commission, he said. "If anyone who wants to complain about human rights violations in Sri Lanka, whether its torture, whether it is rape, we have a system.
The country's leaders accuse journalists of fabricating allegations of atrocities, and stand staunchly by a clan-like government that has alarmed many democracies in the West. Rajapaksa's family has held a firm grip on power since 2005, with one Rajapaksa brother serving as the economy minister, another holding the defense secretary title and a third serving as speaker in a parliament firmly controlled by Rajapaksa's coalition.
For the 53-nation Commonwealth -- which has espoused democracy and human rights as its core values since its founding in 1931 -- the poor publicity threatens to greatly overshadow the meeting unless it can persuade Sri Lanka to cooperate with international demands for an independent war investigation. Despite representing about a third of the planet's population, the group of Britain and its former territories has battled accusations of irrelevancy for years.
Sri Lanka, seeing the summit as a coming-out party after a long and costly civil war with the Tamil Tiger rebels, has tried to sidestep the controversy while busily building roads, expanding its harbor, polishing monuments and gutting slums.
Commonwealth Secretary-General Kamalesh Sharma defended holding the summit in Colombo, saying Thursday it shows "the Commonwealth in action" by allowing Sri Lanka to meet with leaders who have dealt with issues of human rights, rule of law and judicial independence in their countries.
Foreign ministers end a two-day meeting Thursday, while national leaders begin a three-day summit Friday.
Leaders such as British Prime Minister David Cameron have said that engaging Sri Lanka at the summit is preferable to isolating and shaming the country into submission. That engagement includes pressing Sri Lanka to account for thousands of civilians who disappeared in the final months of the war when government forces crushed resistance by Tamil rebels fighting for an ethnic homeland.
A U.N. report in August suggested Sri Lanka's Sinhalese-dominated armed forces may have killed up to 40,000 minority Tamils, while the rebels killed civilians, used them as human shields and forcibly recruited child soldiers.
But Sri Lanka has remained defiant, snubbing the report by U.N. human rights commissioner Navi Pillay, who said she saw no effort by the country to properly investigate despite repeated demands by the U.N. human rights council.
Troops remain heavily deployed throughout the northern Tamil heartland on the teardrop-shaped island off southwest India. Provincial elections held in September were seen as a step toward granting Tamils more autonomy, but also drew criticism for falling far below what is needed for postwar reconciliation.
Canadian Prime Minister Stephen Harper will stay away from the meeting, saying his country was disturbed by ongoing reports of intimidation and incarceration of politicians and journalists, reported disappearances and alleged extrajudicial killings.
Australian Premier Tony Abbott will attend the meeting, though Australian Sen. Lee Rhiannon accused Colombo of trying to "shut down" scrutiny of war crimes after she and a New Zealand lawmaker were detained and questioned for three hours Sunday after preparing a news conference on human rights in Colombo.
