On the night of 14 – 15 March 1939, Ribbentrop played a key role in the German annexation of the Czech part of Czecho-Slovakia by bullying the Czechoslovak President Hácha into transforming his country into a German protectorate at a meeting in the Reich Chancellery in Berlin.

On 20 March 1939, Ribbentrop summoned the Lithuanian Foreign Minister Juozas Urbšys to Berlin and informed him that if a Lithuanian plenipotentiary did not arrive at once to negotiate turning over the Memelland to Germany the Luftwaffe would raze Kaunas to the ground.

In March 1939, Ribbentrop assigned the largely ethnic Ukrainian Sub-Carpathian Ruthenia region of Czecho-Slovakia, which had just proclaimed its independence as the Republic of Carpatho-Ukraine, to Hungary, which then proceeded to annex it after a short war.

Initially, Germany hoped to transform Poland into a satellite state, but by March 1939 German demands had been rejected by the Poles three times, which led Hitler to decide, with enthusiastic support from Ribbentrop, upon the destruction of Poland as the main German foreign policy goal of 1939.

That same day, on 21 March 1939, Ribbentrop presented a set of demands to the Polish Ambassador Józef Lipski about Poland allowing the Free City of Danzig to return to Germany in such violent and extreme language that it led to the Poles to fear their country was on the verge of an immediate German attack.

Ribbentrop had used such extreme language, in particular his remark that if Germany had a different policy towards the Soviet Union then Poland would cease to exist, that it led to the Poles ordering partial mobilization and placing their armed forces on the highest state of alert on 23 March 1939.

On 26 March, in an extremely stormy meeting with the Polish Ambassador Józef Lipski, Ribbentrop accused the Poles of attempting to bully Germany by their partial mobilization and violently attacked them for only offering consideration of the German demand about the " extra-territorial " roads.

Ribbentrop denied correctly that Germany was going to invade Romania, but since his denials were issued in almost identical language to the denials that he had issued in early March, when he denied that anything was being planned against the Czechs, this increased rather than diminished the “ Romanian war scare ” of March 1939.

During the Molotov – Ribbentrop Pact negotiations, Ribbentrop was overjoyed by a report from his Ambassador in Moscow, Count Friedrich Werner von der Schulenburg, of a speech by the Soviet leader Joseph Stalin before the 18th Party Congress in March 1939 that was strongly anti-Western, which Schulenburg reported meant that the Soviet Union might be seeking an accord with Germany.

In public, Ribbentrop expressed great fury at the Polish refusal to allow for Danzig's return to the Reich, or to grant Polish permission for the " extra-territorial " highways, but since these matters were only intended after March 1939 to be a pretext for German aggression, Ribbentrop always refused in private to allow for any talks between German and Polish diplomats about these matters.

On 1 March 1940, Ribbentrop received Sumner Welles, the American Under-Secretary of State, who was on a peace mission for President Franklin D. Roosevelt, and did his best to abuse his American guest.
