Mugabe's Latest Overseas Trip Angers Some ZimbabweansZimbabwe's president is angering some back home with his latest trip overseas, this time to a U.N. conference on oceans even though his country is a landlocked state. The 93-year-old leader Robert Mugabe has been criticized as a "non-resident president" for globe-trotting while the economy crumbles. He has visited Dubai, China, Singapore, Mexico, Ethiopia, Swaziland, South Africa, Ghana, Mauritius and Mali this year alone.\n\nMugabe spoke about the threat of climate change during the U.N. meeting this week. South African broadcaster SABC reported that three aides helped him to the podium for a speech that was "at times stumbling."\n\nDespite his advanced age, reports of ill health and visible signs of slowing down, Mugabe still maintains a busy travel schedule.\n\nZimbabwe's ministry of finance statistics says he spent $36 million on foreign travel in the first 10 months of 2016.\n\nAn opposition leader and former finance minister, Tendai Biti, has repeatedly claimed that during his time in government, Mugabe took at least $4 million for every trip to fund the presidential entourage.\n\n"Self-evident that there must be a law restricting such travel by the president. He behaves like a five-year old," Biti tweeted on Monday when word of Mugabe's visit to the U.N. conference spread.\n\nThe president's spokesman has defended his travels, saying that "diplomacy does not come cheap."
