Mugabe Heads to Asia for Medical Treatment VOA News March 03, 2011 Zimbabwe President Robert Mugabe (file photo) Photo: AP Zimbabwe President Robert Mugabe (file photo) Officials say Zimbabwe President Robert Mugabe is heading back to Singapore Thursday for medical treatment. They did not disclose what treatment the 87-year-old is receiving. Mugabe was in Singapore last month for a check on his cataract following surgery last year. On Wednesday, he threatened to seize foreign-owned businesses, in retaliation for Western sanctions imposed on him and his political allies. Speaking at a rally in the capital, Harare, Mugabe made special mention of British-controlled banks and companies. He said there are more than 400 British firms in Zimbabwe, and singled out two British-run banks, Barclays and Standard Chartered. Mugabe said now is the time to take action against such companies. He also called for a boycott of foreign products. Western countries accuse Mugabe of driving Zimbabwe to ruin with years of political repression and economic mismanagement, especially the seizure of white-owned commercial farms. President Mugabe quipped that Western sanctions have crippled Zimbabwe's economy. .
