FACTBOX-Major changes in Ecuador's proposed constitution

QUITO, July 25 (Reuters) - President Rafael Correa's allies proposed a new constitution late Thursday that would boost the leftist president's powers if a majority of Ecuadoreans approve it in a September referendum.

Here are some of the key constitutional changes approved in a vote at the 130-member assembly on the final draft:

ECONOMY

* The state would have more control and regulation over strategic sectors such as oil, mining and telecommunications, and could tighten regulation on monopolies.

* The president would manage monetary and lending policy instead of the central bank, which would lose its autonomy. Ecuador adopted the U.S. dollar as its official currency in 2000, but Correa has been a critic of the move that aimed to halt the rapid devaluation of the national currency.

* Forbid most international arbitration on future foreign contractual rows.

DEBT

* Create the concept of "illegitimacy" for some foreign loans and promote civilian audits of debt. The measure could give the government powers to repeal debt or a legal base on which to challenge credits in courts.
