White House officials met on Monday with several leaders of venture capital firms and the technology and defense industries to boost the Biden administration’s interest in supporting Ukraine’s access to state-of-the-art American equipment, senior administration officials told Reuters.

“The conversation focused on a number of systems, including unmanned aerial systems, how to counter approaching unmanned aerial systems and dealing with demining,” one of the officials said after the five-hour meeting.

Jake Sullivan, chairman of the White House National Security Council, called the meeting to push for “a renewed focus on helping Ukraine overcome these key technological challenges that he has identified as impeding their progress and momentum on the battlefield,” the second administration, the official said.

Key members of the National Security Council met with industry executives from Fortem Aerospace, defense technology companies such as Palantir Technologies Inc and Anduril Industries Inc, and drone maker Skydio, among others brought to the House.

Jake Sullivan attended at least part of the event, as did his deputy, John Feiner, who presided over part of the meeting, one of the officials said.

Administration officials said Monday’s meeting gave them an opportunity to learn about new opportunities for a deeper cross-section of American industry, with the hope that the government will be able to facilitate these innovations for the benefit of Ukraine.

Officials stressed that any efforts to support Ukraine would be stymied without an additional $100 billion-plus aid package that President Joe Biden has urged lawmakers to approve, which includes about $50 billion in new aid. like $14 billion to Israel in its war against Hamas in Gaza.

Officials said the effort was separate from a December deal to speed up joint weapons production and data sharing between the U.S. and Ukraine.
