Ecuador kicks out 20 US military specialists as there were 'too many of them'
President Rafael Correa had publicly complained in January that Washington had too many military officers in Ecuador, claiming there were 50, and said they had been "infiltrated in all sectors."
At the time, he said he planned to order some to leave.
Weinshenker said the military group had 20 Department of Defense employees, not all of them uniformed, and that Washington had provided $7 million in security assistance to Ecuador last year, including technical training for maintaining aircraft and cooperation in combatting drug trafficking, human trafficking and terrorism.
Weinshenker said US military cooperation in Ecuador dates back four decades and that "all the activities we have carried out have had the explicit approval of our Ecuadorean counterparts."
US relations with Ecuador have been strained in recent years, even before Correa provided asylum in 2012 to WikiLeaks founder Julian Assange, whose organization published troves of leaked US military documents and diplomatic cables highly embarrassing to Washington.
Correa had previously expelled at least three US diplomats including then-Ambassador Heather Hodges in 2011 in response to a cable divulged by WikiLeaks that suggested Correa was aware of high-level police corruption.
In November, Correa's government said it was asking the US Agency for International Development to end operations in the country, accusing it of backing the opposition.
USAID is to end operations in September when programs it is funding have run their course.
Shortly after first taking office in 2007, Correa purged Ecuador's military of officers deemed to have close relations with US counterparts.
He also ended an agreement with Washington that allowed US drug interdiction flights to be based at the Ecuadorean airfield in Manta.
