The United States on Monday imposed sanctions on a major Chinese electronics and engineering company for assisting Venezuela in curbing dissent on the internet.
The US said it was restricting transactions with the China National Electronics Import and Export Corporation (CEIEC), and blocking assets of any firm in which the state-owned company holds a 50 percent stake or higher.
The Treasury Department said CEIEC provides expertise to Venezuela's state-owned telecom company, which has blocked independent media as well as livestreams by opposition leader Juan Guaido, who is recognized as interim president by at least 50 countries, including the US.
"The United States will not hesitate to target anyone helping to suppress the democratic will of the Venezuelan people and others around the world," Treasury Secretary Steven Mnuchin said in a statement.
The Treasury Department described CEIEC as offering a "commercialized version of Beijing's 'Great Firewall,'" the communist power's sweeping filter that scrubs out politically sensitive material from the internet accessible to ordinary people.
CEIEC on its website describes itself as selling "solutions that protect the most basic rights of every citizen," and also mentions business interests in Bolivia and Ecuador.
China is a major supporter and commercial partner of oil-producing Venezuela, helping leftist leader Nicolas Maduro survive a nearly two-year US-led campaign to topple him as he leads an economy in shambles.
Venezuela on Sunday will hold legislative elections in which Maduro hopes to take back the National Assembly, the only institution controlled by the opposition, with Guaido boycotting what he and several international observers see as a rigged process.
US Secretary of State Mike Pompeo said that CEIEC "has been supporting the Maduro regime's malicious efforts to repress political dissent and undermine democratic processes since 2017."
"Maduro's desperate attempts to manipulate the democratic processes should leave no doubt that any elections organized by the illegitimate regime, including the December 6 parliamentary elections, will be neither free nor fair," Pompeo said in a statement.
The Venezuelan government, for its part, denounced in a statement the "illegal actions of the United States government" that it said seek to "destabilize" the country on the eve of parliamentary elections.
President Donald Trump's administration has been ramping up sanctions against adversaries Iran and Venezuela as it prepares to hand over on January 20 to President-elect Joe Biden.
The Treasury Department said CEIEC has more than 200 subsidiaries and offices around the world. Monday's decision allows a 45-day grace period for the company's partners to wind down operations or face US punishment.
CEIEC was previously under US sanctions from 2006 to 2008 under a law that prohibits activities seen as helping weapons proliferation from Iran and Syria.
