The internet companies – Google, Microsoft and Yahoo – are being pressed by a group of US legislators to resist to pressure from communist government of Vietnam. The group of a dozen of US lawmakers is urging these internet giants to resist strongly to the “communist Vietnam's "aggravating" drives to curb online freedom of political expression”.

The group of twelve US lawmakers is comprised of eight Democratic Representatives including Loretta Sanchez, James Moran, Michael Honda, Madeleine Bordallo, Maurice Hinchey, Hank Johnson, Neil Abercrombie, and Niki Tsongas, and four Republican Representatives including Joseph "Anh" Cao, the first Vietnamese American to serve in the House, Daniel Lungren, Ed Royce, and Thaddeus McCotter.

According to Vietnamese-American activists, Hanoi, like China’s communist regime, has escalated its campaigns to repress the progressing blogging practice in Vietnam. Reporters Without Borders has confirmed that Vietnam is suppressing the freedom of expression on Internet. Viet Tan, a pro-democracy group banned in Vietnam, is urging the internet companies not to cooperate with the Vietnam authorities.

Viet Tan activists Duy Hoang, Cuong Nguyen and Angelina Huynh said, “Any collaboration to help the Vietnamese government gain more control over the Internet, like in the case of China, will set back the Vietnamese blogger movement. More bloggers will be arrested and more information will be blocked from Vietnamese citizens.”

In a letter to chief executives of the three internet giants, Eric Schmidt (CEO Google), Steve Ballmer (CEO Microsoft), and Carol Bartz (CEO Yahoo), the twelve US lawmakers wrote, "We write to express our concern regarding the worsening internet restrictions in Vietnam. We are especially concerned by reports that Vietnam's Ministry of Information and Communications may be approaching major internet service providers to request their help in policing the Internet. We strongly urge you to advocate for the freedoms of speech and expression for the citizens of Vietnam by continuing to provide your technologies to the people of Vietnam in a manner that respects their rights and privacy.”
