Lima - President Barack Obama is wrapping up a three-country, post-US election tour the same way it began: by trying to reassure leaders from around the world that US democracy isn't broken and everything will be fine when Republican Donald Trump succeeds him next year.Obama is in Lima for a final appearance at an annual Asia-Pacific summit.But global concerns about Trump's pending ascension to the world's most powerful office after a surprise win in the recent presidential election were expected to be a key topic during Obama's meetings on Saturday and Sunday. The Trump issue overshadowed the president's interactions with world leaders during his earlier stops in Greece and Germany.Trump opened what was an unlikely presidential bid by blasting Mexicans as criminals and rapists and vowing to build a wall along the Mexico border to keep them and other Latinos from entering the US illegally. During the campaign, he rattled US allies by questioning the value of multinational organisations like Nato and and he opposed international trade deals, including a pending Pacific trade pact that Obama negotiated with 11 other countries.Since Obama opened the final foreign trip of his presidency with a stop in Greece on Tuesday, he has tried to reassure his counterparts that the US will uphold its partnerships and obligations despite the divisive rhetoric of a campaign that ended with the election of a real estate mogul and reality TV star with no political or government experience.Stopped growingObama probably offered additional reassurance on Saturday during his meeting with Pedro Pablo Kuczynski, who took office as Peru's president earlier this year. The leaders made no public comments as they appeared before a contingent of US and Peruvian news media.On Friday, before Obama's late-night arrival in Peru's capital, Kuczynski warned that the US presidential election is a sign of intensifying hostility toward free trade that threatens the global economy. He told delegates gathering for the Asia-Pacific Economic Co-operation Forum that global trade had stopped growing in the past two years and would only worsen if nations wall off their economies."It is fundamental that world trade grow again and that protectionism be defeated," said Kuczynski, who did not mention Trump by name.Obama has argued for some time that globalisation is here to stay and governments must address fears about what the changing economics mean for them.
