Sino-German cooperation (1911-1941)
I assume financial aid was being discussed?
Well, Kung and Chinese delegacy took part in King George VI's coronation in 1937 (Kung was by then vice prime minister, secretary of treasury and president of Central Bank of China). After the coronation they visited Germany, invited by Hjalmar Schacht and Werner von Blomberg.
Chinese delagacy arrived at Berlin on June 9 1937. Kung met Hans von Mackensen on June 10 (von Neurath was visiting eastern Europe), during the meeting, Kung pointed out that Japan is not a reliable ally for Germany, he believe that German didn't forget Japanese invasion of Tsingtao and Pacific Islands during WWI. China is the real anti-communist state and Japan is only " flaunting". Von Mackensen promised that there will be no problem in Sino-Germany relationship so far as he and Neurath are in charge of Foreign Ministry. Kung also met Schacht on the same day. Schacht expianed to him that the anti-comintern pact is not an German-Japanese alliance against China. Germany is glad to loan China 100 million Reichsmark and they will not do so with Japanese. (Akten zur deutschen auswärtigen Politik 1918-1945/ADAP
Kung visited Hermann Göring on June 11th, Göring told him he think Japan is a "Far East Italy" (he means Italy broke its alliance and declared war against Germany in WW1), and Germany will never trust Japan (Cheng Tian Fang's Memoir
, volume 13. Cheng was Chinese ambassador to Germany by then). Kung asked Göring "Which country will Germany choose as her friend, China or Japan?", and Göring says China could be a mighty power in the future and Germany will take China as friend.
Kung met Hitler on June 13th. Hitler told Kung Germany has no political or territorial demands in Far East, Germany is a strong industrial country and China is a huge agricultural country, Germany's only thought on China is business. Hitler also hope China and Japan could cooperate and Hitler could mediate any disputes between these two countries, as he mediate the disputes between Italy and Yugoslavia. Hitler also told Kung that Germany will not invade other countries, and is also not afraid of foreign invasion. If Russia dare to invade Germany, one German division could defeat two Russian corps. The only thing he (Hitler) worry about is bolshevism in eastern Europian states, it's a threat to German interests and market. Hitler also said he admire Chiang because he built a powerful centralized government. (Cheng's Memoir
, vol. 13)
Kung met von Blomberg on the afternoon of June 13th, discussed about the execution of 1936 HAPRO Agreement (German Ministry of War loan China 100 million Reichsmark to purchase German weapons and machines, China pay the loan by tungsten and antimony).
Kung left Berlin on June 14th to visit the US, and returned to Berlin on August 10th, one month after Sino-Japanese War broke out. He met von Blomberg, Schacht, von Mackensen and Ernst von Weizsäcker, ask them to mediate the war.
