UPDATE 2-Bolivia nationalizes Spanish-owned airports operator
* Morales says local Abertis unit slacked on investment
* Leftist leader has increased state control over economy
* Spanish companies have been hit by recent takeovers

LA PAZ, Feb 18 (Reuters) - Bolivian President Evo Morales, who has tightened state control over the nation's small economy since taking office in 2006, nationalized an airports operator owned by Spanish infrastructure company Abertis on Monday.
In the latest in a series of state takeovers affecting Spanish-owned companies, the leftist president said Abertis's Sabsa unit had failed to fulfill investment commitments promised almost two decades ago.
"I want to let the people of Bolivia know about the nationalization of Sabsa," Morales said in a televised speech in the central city of Cochabamba, adding that the company had made "an exorbitant profit with a derisory capital input."
"For this and other reasons, we were obliged to take this decision. We were ready to do this years ago, but we waited because of our diplomatic relations with certain countries," he said.
Spanish Prime Minister Mariano Rajoy urged Latin American governments to respect Spain's investments in their economies last month during a summit of European and Latin American leaders in Chile.
Bolivia has taken control of several power transmission and distribution companies in the last year, affecting Spain's Red Electrica and Spanish utility Iberdrola.
An Abertis spokesman in Madrid declined to comment on the takeover, which affects operations at Bolivia's three international airports in Cochabamba, the administrative capital of La Paz and the eastern economic hub of Santa Cruz.
Morales, a close ally of Venezuela's Hugo Chavez who shares his penchant for fiery leftist rhetoric, was elected on pledges to redistribute wealth in South America's poorest country and is highly critical of the privatizations of the free-market 1990s.
One of his first measures was to seize control of the energy industry, Bolivia's biggest foreign currency earner, and he has also nationalized a telecommunications company, several mines and a large tin smelter.
Many of those businesses, including Sabsa, were put into private hands in the 1990s. Other Spanish companies in Bolivia include bank BBVA.
Morales said an independent audit would be carried out to decide how much compensation Abertis would be paid for Sabsa, which stands for Bolivian Airport Services SA. Any outstanding debts would be deducted.
He said the government had negotiated for several months with the company over a nine-year investment plan that envisioned spending of about $56 million, but that "these efforts unfortunately have been in vain."
Earlier this month, a government minister said a Sabsa proposal to invest $36 million was insufficient and that a decision on scrapping the concession would probably be made sometime in February.
Abertis shares were trading down 1.9 percent at 12.635 euros per share following Morales's announcement in afternoon trade in Madrid. (Additional reporting by Jose Elias Rodriguez in Madrid; Writing by Helen Popper; Editing by Theodore d'Afflisio and Andrea Ricci)
