The U.S. will ensure Ukraine is equipped to defeat Russia and rebuild its economy, Secretary of State Antony Blinken said during a visit to Kyiv to show support as its forces press ahead with a grinding counteroffensive.

The top U.S. diplomat met Ukraine’s foreign minister before speaking with President Volodymyr Zelenskyy and other officials as the country’s military tries to expand gains in its months-long campaign over the course of the summer.

Blinken stopped in Kyiv en route to the Group of 20 summit in India, where Russia’s invasion of its neighbor will be a major topic, though President Vladimir Putin won’t be attending. It also gives the U.S. an opportunity to consult before this month’s United Nations General Assembly in New York, where Ukraine will press its case to its allies for continued economic and military backing.
