William Brownfield, the US Ambassador to Venezuela, denied Tuesday any ties between his government and the student demonstrations for freedom of expression held lately nationwide.

Previously, the Venezuelan government pointed to the United States involvement in a plot to overthrow President Hugo Chávez.

"The US government, the US people, the US republic, are not supporting, participating, bolstering or giving a hint to any of those people who march for or against either side. We have exactly the same information that you have available -that of the media," he told reporters.

He added that the United States believes in freedom of expression, freedom of protest, and dialogue as democratic tools, DPA quoted.

"This is the case of the United States. Each country is to decide on its own, on how to respond exactly to the remarks and street activities," Brownfield noted.

President Chávez accused Washington of encouraging a "soft coup," by means of student demonstrations.
