First step is to reduce public spending and fight corruption, just very basic steps will bring significant improvement.

Then, welcome foreign and local investment: privatize most of the industries that were nationalized and are now idle, and fix labor laws a little, this also include liberalization of currency, enforce property laws so private companies feel safe investing in the long term.

When can this happen? As of today no sooner than 2019 when the next presidential elections will take place. Unless a coup is on the table but I don't see that happening.
