Surge in cocaine trade undermines Conde's bid to revive Guinea

* West Africa a major transit point for cocaine into Europe

* Cocaine traffickers returning to Guinea under Conde's government

* Guinea lacks resources to tackle trafficking networks

CONAKRY, Jan 31 (Reuters) - A surge in cocaine trafficking has transformed Guinea into West Africa's latest drug hot spot, jeopardizing President Alpha Conde's efforts to rebuild state institutions after a military coup and attract billion of dollars in mining investment.

Locals and Latin Americans long-accused of smuggling are operating freely in the country, some with high-level protection from within Conde's administration, according to Guinean and international law enforcement officials and internal police reports seen by Reuters.

The growth of trafficking was overlooked as diplomats focused on securing a fragile transition back to civilian rule after the 2008 putsch.

Counter-narcotics agents from the United States and other countries, meanwhile, concentrated on smugglers in neighbouring Guinea-Bissau, a tiny former Portuguese colony dubbed by crime experts Africa's first "narco-state".

However, the U.S. State Department's 2013 International Narcotics Control Strategy Report said seizures in Guinea and cases abroad traced back there show a spike in trafficking since Conde won power at a 2010 election.

A lack of government figures makes estimating volumes tricky, but a foreign security source said one or two planes landed each month last year, ferrying in cocaine from Latin America mostly for smuggling to Europe.

"Whatever the attitude of the head of state, it's clear that traffickers can operate in Guinea. They have deep roots there," said Stephen Ellis, researcher at the African Studies Centre, Leiden, in the Netherlands.

Ellis said drug money was having a corrosive effect on attempts by Conde's government to improve governance: "It's worrying because of the effects not just on the politics of Guinea, but the whole region."

A July report by Guinea's top anti-drugs agency, seen by Reuters, said traffickers were operating with protection of senior civilian, military and police officials. It said proceeds from the trade are laundered through various channels, including real estate, fishing companies and local mining operations.

HIGHWAY 10

Guinea and Guinea-Bissau are at the eastern end of "Highway 10", the nickname given by law enforcement officers for the 10th parallel north of the equator, the shortest route across the Atlantic, used by traffickers over the past decade to smuggle Latin American cocaine destined mainly for Europe.
