Stunning WWII-era Chinese painting satirizing foreign imperialism

I have a huge collection of Sinophobic political cartoons dating back to the 19th century. However, this one shows the Chinese were just as able to dish it out to the West!

Pictured above,

Chinese satirical print (ca. 1938) showing world leaders at the peace table playing a game of mahjong. Characters include: Chiang Kai-shek, Mussolini, Hitler, Lin Sen (Chairman of the Nationalist government), Édouard Daladier (French Prime Minister), Kazushige Ugaki (Japanese Foreign Minister), Maxim Litvinov (Soviet Foreign Minister), Wang Chonghui (Chinese Foreign Minister), Neville Chamberlain and Franklin D. Roosevelt.

Publisher is named as the ‘Changchun Book Company’, with text at the top reading something like ‘A Relaxing Picture of World Peace’ while the text at the bottom reads (in a presumably garbled translation of the text at the top) ‘The World Peace of Relaxes Picture’.

Identifications may not be correct, also not sure who the person sat between Chiang Kai-shek and Lin Sen is.
