[economic] negotiations' as a result of earlier German procrastination." By June 1939, thanks to information sold by Scheliha, the Soviets knew that Germany was committed to an invasion of Poland later that year. Tripartite talks progress and Baltic moves On June 2, the Soviet Union insisted that any mutual assistance pact should be accompanied by a military agreement describing in detail the military assistance that the Soviets, French and British would provide. That day, the Soviet Union also submitted a modification to a French and British proposal that specified the states that would be given aid in the event of "direct aggression", which included Belgium, Greece, Turkey, Romania, Poland, Estonia, Latvia and Finland. Five days later, Estonia and Latvia signed non-aggression pacts with Germany, creating suspicions that Germany had ambitions in a region through which it could attack the Soviet Union. British attempt to stop German armament On June 8, the Soviets had agreed that a high ranking German official could come to Moscow to continue the economic negotiations, which occurred in Moscow on July 3. Thereafter, official talks were started in Berlin on July 22. Meanwhile, hoping to stop the German war machine, in July, Britain conducted talks with Germany regarding a potential plan to bail out the debt-ridden German economy, at the cost of one billion pounds, in exchange for Germany ending its armaments program. The British press broke a story on the talks, and Germany eventually rejected the offer. As the Soviets were reading the British diplomatic codes in 1939, the Kremlin was well informed about the general thrust of the British policy to build a "peace front" meant to "contain" Germany. Tripartite talks regarding "indirect aggression" After weeks of political talks that began after the arrival of Central Department Foreign Office head William Strang, on July 8, the British and French submitted a proposed agreement, to which Molotov added a supplementary letter. Talks in late July stalled over a provision in Molotov's supplementary letter stating that a political turn to Germany by the Baltic states constituted "indirect aggression", which Britain feared might justify Soviet intervention in Finland and the Baltic states or push those countries to seek closer relations with Germany (while France was less resistant to the supplement). On July 23, France and Britain agreed with the Soviet proposal to draw up a military convention specifying a reaction to a German attack. Soviet-German political negotiation
