What diplomatic engagements are taking place between US officials and international leaders regarding the Ukraine conflict?

At the Munich Security Conference, key US officials including Vice President J.D. Vance and Secretary of State Marco Rubio are conducting high-level diplomatic meetings with international leaders to address the ongoing Ukraine war. Most notably, Vance is meeting with Ukrainian President Volodymyr Zelensky to strengthen US support for Ukraine's defense efforts. However, Vance's decision to skip scheduled talks with German Chancellor Olaf Scholz has created diplomatic concerns. Congressman Jason Crow emphasizes that bipartisan US support and strong international alliances remain crucial for effectively countering Russian aggression and supporting Ukraine's sovereignty. These diplomatic exchanges represent shifting dynamics in US foreign policy and demonstrate the complex international coordination required to address the Ukraine crisis through diplomatic channels.
