Accusations about the handling of Palace Museum finances began to dog Li and his protégé, Yi Peiji. To pay for ambitious cataloging and publication projects Yi had sold off gold dust, silver, silk, and clothing without government approval. In October 1933, after several years of investigations which Li had fought, a procurator brought formal charges against both men, with another round of indictments a year later and further charges against Yi in 1937. Yi fled to the Japanese concession at Tientsin and Li could move about in Shanghai and other coastal concessions only in disguise. In 1932, Li traveled to Geneva, Switzerland, to organize the Chinese delegation to the International Committee on Intellectual Cooperation of the League of Nations. While at Geneva he established the Sino-International Library. During World War II, Li lived for most of the time in New York, with trips to Chongqing and Kunming. After the 1941 death of his first wife in Paris, he was reported to have a relation with a Jewish woman named "Ru Su" ("Mrs. Vegetarian"?), but they did not marry. He served as a cochairman of the Emergency Committee to Save the Jewish People of Europe, an offshoot of the Bergson Group, which lobbied the US government and took out advertisements in newspapers urging American intervention to save European Jews. In 1943 and 1944 he was a featured speaker at the Committee's Emergency Conferences to Save the Jewish People of Europe. Following the war, Li returned once again to China. As Rector of the National Peiping Research Academy Li was a delegate to the First Soya Congress in Paris, March 1947. The Congress was organized by the French Bureau of Soya ("Bureau Français du Soya"), the Laboratory of Soya Experiments ("Laboratoire dEssais du Soya"), and the France-China Association ("lAssociation France-Chine"). As communist armies approached Beijing in 1948, Li moved to Geneva, where he and his wife remained until 1950, when Switzerland extended recognition to the People’s Republic. He then moved to Montevideo, Uruguay. After his wife died there in 1954, Li established a second home in Taiwan and resumed his role as national policy advisor to Chiang Kai-shek and a member of the Central Appraisal Committee, which superseded the Central Supervisory Committee. In 1958, one of Li's last public acts was to dedicate a middle-school in Tainan named in honor of his friend, Wu Zhihui.
