The United States' Under Secretary of State Sumner Welles issues a declaration on the U.S. non-recognition policy of the Soviet annexation and incorporation of three Baltic states: Estonia, Latvia and Lithuania.

The Welles Declaration was a diplomatic statement issued on July 23, 1940, by Sumner Welles, the acting US Secretary of State, condemning the June 1940 occupation by the Soviet Union of the three Baltic states (Estonia, Latvia, and Lithuania) and refusing to recognize their annexation as Soviet republics. It was an application of the 1932 Stimson Doctrine of nonrecognition of international territorial changes that were executed by force and was consistent with US President Franklin Roosevelt's attitude towards violent territorial expansion.The Soviet invasion was an implementation of its 1939 MolotovRibbentrop Pact with Nazi Germany, which contained a secret protocol by which both powers agreed to partition and annex the independent states between them. After the pact, the Soviets engaged in a series of ultimatums and actions ending in the annexation of the Baltic states during the summer of 1940. The area held little strategic importance to the United States, but several legations of the US State Department established had diplomatic relationships there. The United States and the United Kingdom anticipated future involvement in the war, but US non-interventionism and a foreseeable BritishSoviet alliance deterred open confrontation over the Baltic states.

Welles, concerned with postwar border planning, had been authorized by Roosevelt to issue stronger public statements that gauged a move towards more intervention. Loy Henderson and other State Department officials familiar with the area kept the administration informed of developments there, and Henderson, Welles, and Roosevelt worked together to compose the declaration.

The declaration established a five-decade nonrecognition of the annexation. The document had major significance for overall US policy toward Europe in the critical year of 1940. The US did not engage the Soviet militarily in the region, but the declaration enabled the Baltic states to maintain independent diplomatic missions, and Executive Order 8484 protected Baltic financial assets. Its essence was supported by all subsequent US presidents and congressional resolutions.

The Baltic states re-established their independence in 1990 and 91.

Under Secretary of State (U/S) is a title used by senior officials of the United States Department of State who rank above the Assistant Secretaries and below the Deputy Secretary.

From 1919 to 1972, the Under Secretary was the second-ranking official at the Department of State (immediately beneath the United States Secretary of State), serving as the Secretary's principal deputy, chief assistant, and Acting Secretary in the event of the Secretary's absence. Prior second-ranking positions had been the Chief Clerk, the Assistant Secretary of State, and the Counselor. Prior to 1944, a number of offices in the Department reported directly to the Under Secretary. In July 1972, the position of Deputy Secretary superseded that of Under Secretary of State.
