Mosbacher is stepping down as US ambassador to Poland as Joe Biden is set to be sworn in as the next president on Wednesday to take over from Donald Trump.
“One of the greatest honors of my life was when President Trump asked me to become the United States ambassador to Poland,” she said in a video message released on the eve of Biden’s inauguration.
“I am incredibly proud of our joint work to advance US-Polish relations,” she added.
“Every minute I have spent in Poland has been a joy, and I have a deep affection for the Polish people,” she also said.
“Sadly, my time here has come to an end. I will step down as US ambassador to Poland on January 20th in line with a long-standing tradition,” she added.
Looking back at her time in Warsaw, Mosbacher listed some of her accomplishments during her tenure as ambassador:
“Thanks to the incredible work of my team here at the embassy, I am especially proud that during my tenure Poland joined the Visa Waiver Program. This is a historic milestone that ensures our people-to-people ties remain strong for decades to come.
“We’ve also delivered on energy security by signing a nuclear intergovernmental agreement to help Poland decisively move ahead in building nuclear power plants with American technology.
“Throughout my tenure, I have consistently and successfully advocated for the Three Seas Initiative as a means of driving regional economic growth and bolstering trans-Atlantic ties.
“We have strengthened the eastern flank of NATO by signing the Enhanced Defense Cooperation Agreement and establishing the 5th Corps Forward Command in Poznań.
“These accomplishments will last long after I’ve left, leaving an indelible mark on the enduring friendship, partnership and alliance between the United States and Poland.”
Mosbacher also told the Polish people in her message that she would miss her time in their country and that she intended to come back and visit often.
Earlier this month, Mosbacher said in a statement that Polish-US relations were strong and likely to stay that way after Joe Biden takes office in Washington.
Mosbacher took up her post as ambassador to Poland in September 2018.
