Feb 22 Foreign direct investment in Mexico rose by a fourth last year to reach $28.382 billion, the country's economy ministry said in a statement on Sunday. The ministry said the stronger 2015 FDI was due to U.S. telecoms company AT&T Inc paying more than $2 billion to acquire Mexican wireless operators Iusacell and Unefon, as well as the purchase of Vitro's glass container business by U.S.-based Owens-Illinois Inc for about $2.15 billion.
