Bolivian President Evo Morales on Friday accused the United States of continuing to plot against his government via embassy personnel.

Bolivia expelled Philip Goldberg, the U.S. ambassador to La Paz, eight years ago, saying the envoy conspired to strengthen Bolivia’s right-wing political opposition against Morales’ progressive left-leaning government.

“Despite the expulsion…the U.S. government doesn’t stop in its zeal to conspire against our democratic and cultural revolution,” Morales said through his Twitter account.

The complaint comes a day after Interior Minister Carlos Romero met with U.S. Charge d’Affaires Peter Brennan, who acknowledged having met with opponents to the government.

According to the Bolivian News Agency (ABI), Romero told Brennan that the meetings with opposition leaders “antagonized” the bilateral relationship and were considered interferring in domestic affairs.

On Thursday, minister of the Bolivian Presidency, Juan Ramon Quintana, was on hand for the presentation of a book titled “BoliviaLeaks,” on U.S. attempts to derail Morales’ first term (2006-2010).

As Bolivia’s first indigenous president, Morales launched major reforms to empower the indigenous population, including nationalizing the oil industry, which had been under the control of foreign multinationals.

The United States considers Bolivia a nightmare, fearing our “process of reforms can spread to other countries on the continent,” said Quintana.
