PORT LOUIS (Reuters) - - Mauritius' trade deficit widened 21.1 percent to 7.47 billion rupees ($239.42 million) in August from a year earlier driven largely by higher imports of fuels and lubricants, data showed on Tuesday. The value of imports climbed 13.6 percent to 15.73 billion rupees, with the cost of fuels and lubricants rising to 3.84 billion rupees from 2.64 billion rupees in August last year, Statistics Mauritius said in a statement. Exports rose 7.5 percent to 8.26 billion rupees, the data showed. United Arab Emirates was the main buyer of goods from Mauritius in August, accounting for 17.3 percent, overtaking Britain. India and Chine supplied 24.5 percent and 14.9 percent respectively of the island nation's imports. (1 US dollar = 31.2000 Mauritius rupee)
