Caracas, March 9, 2015 (Venezuelanalysis.com) – U.S. President Barack Obama issued an executive order this Monday slapping Venezuela with new sanctions and declaring the Bolivarian nation an "unusual and extraordinary threat to the national security".

The sanctions target seven individuals accused by the White House of alleged human rights violations and "public corruption", freezing their assets and barring entry into the U.S.

The figures include Justo Jose Noguera Pietri, President of the state entity, the Venezuelan Corporation of Guayana (CVG) and Katherine Nayarith Haringhton Padron, a national level prosecutor currently taking the lead in the trials of several Venezuelan political opposition leaders, including Leopoldo Lopez.

The executive order is the latest in a series of U.S. sanctions imposed on Venezuela over the past few months. On February 3, the Obama administration expanded the list of Venezuelan officials barred from entering the U.S., which now includes the Chief Prosecutor Luis Ortega Diaz.

"Venezuelan officials past and present who violate the human rights of Venezuelan citizens and engage in acts of public corruption will not be welcome here, and we now have the tools to block their assets and their use of U.S. financial systems," announced White House spokesman Josh Earnest.

The U.S. has failed thus far to disclose evidence that might bolster its claims of human rights violations, leading Venezuelan and other regional leaders to condemn what they regard as the arbitrary and political character of U.S. sanctions.

While regional bodies such as the Union of South American Nations (UNASUR) have called for dialogue, Washington has so far refused to support negotiations or to recognise the organisation's stance.

"We will continue to work closely with others in the region to support greater political expression in Venezuela, and to encourage the Venezuelan government to live up to its shared commitment, as articulated in the OAS Charter, the Inter American Democratic Charter, and other relevant instruments related to democracy and human rights," reads the latest White House statement.

The order goes on to call for the release of all "political prisoners" allegedly held by the Venezuelan government, including "dozens of students".

The Venezuelan government, for its part, maintains that all of those arrested are in the process of facing trial for criminal offences linked to violent destabilization efforts spearheaded by the opposition.

Former Caracas Metropolitan Mayor Antonio Ledezma was arrested last month on charges of conspiracy and sedition related to the February 12 thwarted "Blue Coup" attempt. A Venezuelan judge found sufficient evidence linking the opposition figure to air force officials involved in the coup as well as to rightwing terrorist leaders such as Lorent Saleh, who was extradited by Colombian authorities to face charges last year.

The other high profile Venezuelan opposition leader currently facing trial is Leopoldo López, who was indicted for his role in leading several months of violent opposition protests last year with the aim of effecting the "exit", or ouster, of the constitutional government. Known as the "guarimbas", these violent protests and street barricades caused the death of 43 people, the majority of whom were security personnel or Chavistas.

Ledezma and López, together with far right leader Maria Corina Machado, were active in the 2002 coup against then president Hugo Chávez, which succeeded in temporarily ousting the Venezuelan leader until he was restored by a popular uprising.

All three opposition leaders also signed a "National Transition Agreement" released on the day prior to February's "Blue Coup" attempt, describing the government of Nicolas Maduro as in its "terminal phase" and declaring the need to "name new authorities" without mentioning elections or other constitutional mechanisms. Many political commentators interpreted the document as an open call for a coup against the president.

The Venezuelan government has charged the U.S. government with hypocrisy on the issue of human rights, and in particular the mass repression and incarceration of Afrodescendent communities in the U.S.

On February 28, President Maduro announced new measures imposing a reciprocal travel visa requirements on U.S. citizens seeking to enter Venezuela as well as mandating a reduction in U.S. embassy staff to levels that match the number of Venezuelan personnel in Washington.

Maduro also announced the creation of an "anti-terrorist list" of individuals barred from entering Venezuela, which will include former U.S. officials such as George W. Bush and Dick Cheney, who have reportedly "committed human rights violations."

Venezuelan Foreign Minister, Delcy Rodriguez, has confirmed that the Bolivarian government will soon issue an official response to the order.
