With nearly 2,000 lawyers across 45 offices spanning the United States, Europe, Asia, Oceania, and the Middle East, K&L Gates LLP brings deep cross-border legal capabilities to businesses operating in complex and high-growth markets. The firm advises clients on energy, including oil and gas, nuclear, and renewables, infrastructure and construction, defense, financial services, technology, manufacturing, transportation, intellectual property, regulatory policy, litigation and other critical sectors. This breadth of knowledge is particularly relevant as Ukraine advances reforms, attracts international capital, and implements large-scale recovery and reconstruction initiatives. K&L Gates’ experience advising multinational corporations, financial institutions, public sector entities, and emerging growth companies positions it to contribute meaningfully to strengthening Ukraine’s legal and investment environment.
“Ukraine is a market of strategic importance, particularly in energy, mining, infrastructure, defense, and technology,” said Maria Kostytska, Partner at K&L Gates LLP with a decade of experience in that market. “By joining USUBC, we look forward to working closely with American and Ukrainian businesses to support responsible investment, facilitate dispute prevention and resolution, and help create a transparent and predictable legal framework that encourages long-term growth.”
Guillermo Christensen, Partner at K&L Gates in Washington, D.C., and a former US diplomat and CIA intelligence officer, notes, “We have been on the ground in Ukraine supporting our clients, including in the reconstruction and security sectors. The partnership with USUBC offers a valuable platform for us to expand the access and resources we can contribute to U.S. clients keen to enter or expand their footprint in Ukraine.
“We are delighted to welcome K&L Gates to our growing community of leading international law firms,” said Irina Paliashvili, President & CEO of U.S.-Ukraine Business Council. “Their global platform and deep sectoral expertise will be invaluable to our members, particularly as Ukraine accelerates its recovery and integration into global markets. We look forward to productive cooperation and impactful joint initiatives in the months ahead.”
