The country is not planning to change it's three-tiered exchange rate system in the short term, said the official, adding that the government is working on plans to increase dollar revenue by developing mining and petrochemical projects and reduce its dependence on oil.

One US dollar is currently worth 725 bolivars on the black market, which Venezuelans use when they can't get government approval to purchase foreign currency at the three official exchange rates of 6.3, 12.8 and 200.

Venezuela's monthly minimum wage of 7,422 bolivars equates to about $US37 at the weakest legal exchange rate and is only $US10 at the black market rate.

A unified exchange rate would not be possible until the economy becomes more diversified and domestic production rises, said the official.

Press officials at the central bank and finance ministry declined to comment when contacted by telephone Wednesday.

The black market rate is being manipulated by traders in Cucuta, Colombia and the Miami-based website dolartoday.com, the official added. While the rate has become a reference for some minor sectors of the economy, it's a small market and not representative of the overall economy, the official said.

Venezuela maintains its willingness to pay foreign debt and is buying back bonds when it can, said the official, adding that the government could consider selling or swapping gold reserves if it needed to. Gold currently held in Caracas could easily be transported abroad if the need arose, the official said.

The country's foreign reserves fell to a 12-year low of $US15.4 billion on July 27 and have since rebounded to about $US16.5 billion, according to data compiled by Bloomberg.

New loans from China will slowly be reflected in the country's reserves, the official said.
