HARARE, June 7 (Xinhua) -- Zimbabwe's opposition MDC Alliance on Thursday launched its election policy document in which it promises to implement diverse and innovative polices that will transform Zimbabwe into a middle income economy by 2023.

Party president Nelson Chamisa launched the policy document dubbed Sustainable and Modern Agenda for Real Transformation (SMART) under the theme "Behold the New. Change that Delivers."

Chamisa said once elected into office, his government will implement policies that will revamp and modernize the country's dilapidated infrastructure, accelerate economic growth and improve the living standards of the people.

He said their aim was to make Zimbabwe a 100 billion dollars economy by 2029 through aggressive foreign investment attraction, trade facilitation and efficient utilization of the country's natural resources.

"This document is a transformation document. It will change your lives. It's an answer to all the challenges that Zimbabwe faces," said the 40-year old Chamisa who will challenge President Emmerson Mnangagwa in the July 30 election.

The ruling ZANU-PF party launched its election manifesto last month under the theme "Unite, fight corruption, develop, re-engage, create jobs."
