Michelle Bachelet was elected as Chile's president again on Sunday in a landslide victory that hands the center-leftist the mandate she sought to push ahead with wide-reaching reforms. Bachelet won with about 62 percent support, the highest proportion of votes any presidential candidate has obtained since Chile returned to holding democratic elections in 1989.

Brazilian President Dilma Rousseff's popularity continued to recover in November thanks to her government's social programs and a slowdown in inflation, a poll showed on Friday, making her the clear favorite in next year's presidential vote. Seventy-five percent of respondents rated Rousseff's government "good/great" or "average" in the latest Ibope/CNI poll. That was up from 72 percent in September and 65 percent in July, when millions of Brazilians took to the streets to protest poor public transportation, corruption and crime.

People around the world see China as "confident", "belligerent" and "arrogant", state-run media says, in an unusually direct survey of attitudes towards the country. Only 13 per cent of respondents in the poll by the Global Times newspaper described China as "peaceful", a sign that Beijing's territorial spats with its Asian neighbours have taken a toll on its image.

During Tuesday's memorial service for former South African president Nelson Mandela, as tens of thousands gathered in the FNB stadium in Johannesburg and millions more watched on television, an entirely different story emerged: the ten-second interaction between U.S. President Barack Obama and Cuban president Raul Castro.

“We’ve spent decades making their toys, their shoes, and even their flags,” a deep voice intones in Mandarin as US military tanks trundle across a desert. ”All the while, enduring their condescension and biding our time…finally the moment has come; now they will know our greatness.” A group of American soldiers looks up at the sky that suddenly fills with screaming jets, missiles, explosions, fire and fumes.

U.S. political leaders have long spoken of America’s democracy as pivotal to its role in the world, whether it was Woodrow Wilson declaring in 1917 that the U.S. must enter World War I to make the world “safe for democracy,” or George W. Bush saying, on his re-election in 2004, that “It is the policy of the United States to seek and support the growth of democratic movements and institutions in every nation and culture.”

U.S. Secretary of State John Kerry urged the Ukrainian government on Tuesday to “listen to the voices of its people” after President Viktor Yanukovych's decision to spurn an agreement with the European Union sparked days of massive protests. Kerry said Ukrainians had demonstrated “in unbelievable numbers” their support of the accord on closer ties with Europe, which Yanukovych rejected last week in favor of Russian incentives.
