"Together, Secretary (of State Colin) Powell and I notified all financial institutions in the United States to block the assets of 39 additional persons and entities that are either wanted terrorists or who are known to financially support terrorism," Treasury Secretary Paul O' Neill said at a news briefing.
The list included businesses and charitable organizations that the United States says funnel money to Saudi terrorism suspect Osama bin Laden's al Qaida network. Washington says bin Laden is behind the Sept. 11 terrorist attacks on New York and Washington that killed more than 6,000 people.
As part of its war on global terrorism, the United States has tried to choke off the networks' money supply.
Friday's list includes the names and assets of the FBI's 22 most-wanted terrorists, a list that was released earlier this week.
All U.S. citizens and businesses are banned from doing business with the people and organizations on the list.
"We coordinated this blocking order with our allies around the world, and many of them instituted blocking orders today as well," O'Neill said. "Together with the State Department, we've built an international coalition to disrupt the terrorist financing network."
The Treasury said the economic effort was also being helped by 110 foreign governments and the Group of Seven countries.
"As these names have gone out this morning, the G7 countries are taking action to block these accounts in exactly the same way as the United States ... therefore providing a global effort to block and freeze the accounts of all these individuals and organizations,'' a Treasury official said.
The list is in addition to another list released Sept. 24 that marked the beginning of efforts to wage a worldwide financial war on terror networks. That list had 27 entities on it.
The list released Friday has six entities and 33 individuals.
"Thirty-nine names have been added to the president's Sept. 24 executive order," a Treasury official said. "In addition to the 21 new names listed here today ... Treasury's Office of Foreign Assets Control has also instructed U.S. banks to freeze the assets of 18 of the 22 FBI's most-wanted terrorists. The remaining four have already been named by the president in the annex to the Sept. 24 executive order."
Additional names will be added to the list, the official said.
Officials said terrorists often used "creative" methods to transfer funds internationally. Two of the companies of Friday's list were honey businesses; a third was a baker.
Officials said $20 million had been blocked since the Sept. 11 attacks.
