CARACAS -- Venezuela's acting president Delcy Rodriguez said Sunday that differences with the United States would be resolved through diplomatic channels.

Speaking at an event with oil workers at the Puerto La Cruz refinery in northeastern Venezuela, Rodriguez said her government would address long-standing disputes with Washington "face to face" through what she described as Bolivarian diplomacy.

"We are not afraid, because what must unite us as a people is guaranteeing peace and stability for this country," Rodriguez said.

She said Venezuela never imagined that a South American capital would be subjected to a military attack by a foreign power, referring to the event on Jan 3, when US forces attacked Caracas and took by force President Nicolas Maduro and his wife.

Rodriguez called for national unity and urged Venezuelans to resolve internal differences through domestic political dialogue, without foreign interference.

"Enough of orders from Washington to politicians in Venezuela," she said. "Venezuela must resolve its own differences and conflicts."
