The US Department of State congratulated Bulgaria on March 3. On behalf of the United States of America, please accept my warmest congratulations on your Day of Liberation, US Secretary of State Marco Rubio said in a congratulatory message published on the website of the U.S. Department of State.

''After 122 years of diplomatic relations, the friendship and close cooperation between our governments continues to grow.  Constructing new, American-designed nuclear reactors will make Bulgaria’s energy supply more stable and secure and strengthen our bonds.  Our defense cooperation, including Bulgaria’s recent investments to modernize its armed forces, enhances Bulgaria’s security and demonstrates its valuable contribution to NATO, bolstering our collective security.

We look forward to continuing our strong friendship and wish all Bulgarians the best as you celebrate your national day'', the press statement said.
