Ukrainian President Volodymyr Zelenskiy says he has “high expectations” for a second round of meetings scheduled for next week of the partner countries supplying weapons to Ukraine.

Zelenskiy told reporters on May 21 that he expects positive responses to his requests for multiple-launch rocket systems (MLRS) and U.S. jets at the meetings, scheduled to take place on May 23 online in a follow-up to a meeting of about 40 ministers from countries backing Ukraine militarily held last month at the U.S. air base at Ramstein, Germany.

“To be honest, we have high expectations. I would call it a long-awaited process. We are grateful for the great military support provided by various states. We expect a positive [response] on the supply of MLRS,” Zelenskiy was quoted as saying in response to questions from reporters following talks with Portuguese Prime Minister Antonio Costa in Kyiv.

“I have no secrets, we appeal to all countries — from the United States to every European country on MLRS,”

He said the MLRS “just stand still” in other countries but would be “key” to Ukraine’s ability to take the initiative and liberate its territory.

Zelenskiy also addressed reservations expressed by some countries that Kyiv will use rocket systems to attack Russia, saying those who have such concerns should consider that the war continues on Ukrainian territory, including the Donbas area.

“These are our territories, and we are going step by step to liberate them. We cannot pay the price of tens, hundreds of thousands of people. So please help us,” he said.

Costa became the latest Western leader to visit Kyiv. In addition to meeting Zelenskiy, the Portuguese leader met Prime Minister Denys Shmyhal and signed an agreement for unspecified financial support.

Kyiv also got another huge boost of aid from the United States when U.S. President Joe Biden signed a bill to provide nearly $40 billion in military, economic, and humanitarian aid to the country.

“Look forward to new, powerful defense assistance. Today it is needed more than ever,” Zelenskiy said on Twitter.
