Overview
The Institute of Pacific Relations (IPR) was an international nongovernmental organization established in 1925 as a forum for examining political, economic, social, and cultural relations among the countries and territories of the Pacific Rim. It emerged from two related organizing efforts: one centered in New York and associated with Edward C. Carter and the liberal Protestant network known as The Inquiry, and another based in Hawaii and supported by local business interests. The organization reflected the internationalist outlook that developed in the United States after the First World War. Its organizers believed that the United States had acquired a larger role in world affairs and that informed discussion, international cooperation, and liberal democratic values could reduce conflict across the Pacific. The IPR was structured around national councils linked through an International Secretariat. The Secretariat initially operated from Honolulu and coordinated conferences, research, publications, and administrative work, while national councils conducted programs in their own countries and regions. Participants generally came from universities, business, journalism, public affairs, and government-related circles. The organization was not a commercial brand or membership business in the ordinary sense; its principal outputs were conferences, policy discussions, commissioned studies, educational activity, and publications. Financial support came substantially from philanthropic foundations and private donors, particularly the Rockefeller Foundation, with additional assistance associated with the Carnegie Foundation and business communities. The organization’s signature international conferences began in Honolulu in 1925 and 1927, followed by meetings in Kyoto, Hangzhou, Shanghai, Banff, Yosemite, and Virginia Beach before the Second World War. These gatherings addressed trade, colonialism, nationalism, racial relations, economic development, security, and the changing relationship between Asian and Western powers. The 1931 conference was disrupted by Japan’s invasion of Manchuria: the meeting moved from Hangzhou to Shanghai, and Japanese participation later ceased. The IPR sought broad regional representation, including colonial territories such as the Philippines and Korea, although participation varied according to government policy and political circumstances. After the International Secretariat moved to New York in the early 1930s, the American Council became the most influential national council. Carter and his colleagues expanded the organization’s research and educational work, including support for scholarship on Chinese, Japanese, Central Asian, and Southeast Asian history and society. In 1932, the organization developed its bulletin into Pacific Affairs, a quarterly journal that became one of its most visible continuing publications. IPR-sponsored research also included major work on Chinese history, land and labor, political economy, and the interpretation of Asian social change. During the Second World War, the IPR held major conferences at Mont Tremblant, Quebec, in 1942 and Hot Springs, Virginia, in 1945. These meetings discussed postwar reconstruction, colonial rule, international trade, tariff preferences, the political future of Japan, and the implications of anti-colonial nationalism. Their unofficial format enabled academics, business figures, diplomats, and political leaders to debate issues that official diplomatic channels could not always address openly. The organization therefore exerted influence beyond its relatively modest institutional size. The IPR’s internationalist and anti-colonial positions, its willingness to publish Marxist and pro-Soviet analyses alongside opposing views, and the political affiliations of some associates later made it a target of anti-Communist investigations in the United States. Critics argued that the organization had been penetrated by Communists and had influenced American policy toward China. These accusations intensified after the Chinese Communist Revolution, the Amerasia investigation, and the emergence of the Venona material. In the early 1950s, the Senate Internal Security Subcommittee reviewed thousands of IPR documents and questioned personnel. The organization lost its United States tax-exempt status in 1955 after an Internal Revenue Service determination that it had engaged in partisan or controversial policy activity. The IPR pursued litigation under William L. Holland, and a later court judgment rejected the principal IRS allegations, but the organization’s financial and institutional position had already weakened. By the mid-1950s, the growth of university-based Asian studies centers also reduced the IPR’s distinctive role. Major universities attracted foundation funding that had previously supported independent organizations of this type. The combined effects of political controversy, legal costs, changing philanthropic priorities, and competition from academic institutions led to the IPR’s decline and eventual disappearance as an active international organization.
History
The Institute of Pacific Relations was created in 1925 through parallel organizing efforts in New York and Hawaii. Edward C. Carter led the New York initiative, drawing on his experience with the YMCA, The Inquiry, liberal Protestant internationalism, and networks that included academic and philanthropic figures. Ray Lyman Wilbur of Stanford University argued that Pacific affairs required an organization distinct from established East Coast foreign-policy groups. In Hawaii, local business interests were developing a related initiative. The two efforts joined in a structure based on national councils and an International Secretariat. The first IPR conference took place in Honolulu in 1925, with a second Honolulu meeting in 1927. Subsequent conferences were held in Kyoto in 1929; Hangzhou and Shanghai in 1931; Banff in 1933; Yosemite in 1936; and Virginia Beach in 1939. The organization published conference background material and discussions in the Problems of the Pacific series. It attempted to include the full Pacific region, including colonial territories and the Soviet Union, although participation was affected by government restrictions and rising tensions. Japan’s invasion of Manchuria disrupted the 1931 conference, which moved from Hangzhou to Shanghai. Japan later withdrew from the IPR process, and later conferences proceeded without Japanese representation. The increasingly severe conflict between China and Japan, combined with debate over Soviet participation and Marxist scholarship, made the organization more politically controversial. At the same time, the IPR expanded its research role. Its American Council commissioned and subsidized studies on Asian history, economics, politics, and society. Projects included work on Chinese dynastic history and studies of land, labor, geography, and political economy. In 1932, its bulletin was developed into Pacific Affairs, a quarterly journal. Carter became Secretary General in 1933 and successfully moved the International Headquarters to New York. The American Council subsequently became the dominant national body. During the Second World War, the IPR held conferences at Mont Tremblant in 1942 and Hot Springs in 1945. These meetings examined colonial policy, postwar reconstruction, trade, tariff preferences, Japan’s political future, and anti-colonial nationalism. Participants debated the tension between European imperial systems and American economic power, as well as the limits of Western claims about self-determination. After the war, the IPR was attacked by Alfred Kohlberg and other critics who alleged that Communist sympathizers had gained influence within the organization. Its association with Amerasia, overlapping personnel, and the presence of individuals later accused or identified in anti-Communist investigations intensified suspicion. The organization was accused of helping to shape an excessively favorable United States view of Chinese Communism and was sometimes blamed rhetorically for the loss of China, although those broader claims have not generally been accepted by historians as established fact. The Senate Internal Security Subcommittee conducted a major investigation in the early 1950s, reviewing IPR files and questioning personnel. In 1955, the IRS revoked the IPR’s tax-exempt status, arguing that the institute’s activity was controversial and partisan. William L. Holland led the organization’s legal effort to challenge the decision. The litigation continued until 1959, when the final judgment rejected the principal IRS allegations. Nevertheless, the investigation and legal dispute damaged fundraising and public standing. By the mid-1950s, university Asian-studies centers at institutions such as Harvard, Yale, Berkeley, Michigan, and Columbia were also attracting foundation resources and performing work once associated with independent organizations like the IPR. The institute consequently declined and eventually ceased operating as an active organization.

Pacific Affairs
A quarterly journal developed from the IPR bulletin in 1932. It published research and commentary concerning Asian and Pacific political, economic, social, and international affairs. The journal represented the organization’s effort to broaden public and academic understanding beyond conference participants and to provide a continuing outlet for competing interpretations of regional developments.
Conference publication series · 1925
Problems of the Pacific
A series of volumes containing background papers and roundtable discussions from IPR conferences. The publications addressed trade, colonial administration, nationalism, racial politics, economic development, security, and postwar planning, preserving the organization’s principal method of bringing specialists from different Pacific countries into structured debate.
Historical research project
Chinese Dynastic History Project
An IPR-supported scholarly project directed by Karl Wittfogel that sought to translate and annotate official Chinese dynastic histories. It exemplified the institute’s investment in long-term research intended to improve Western understanding of Chinese political and social development.
Controversies
1955
Loss of federal tax exemption
The IRS revoked the IPR’s tax-exempt educational status, alleging partisan propaganda and efforts to influence government opinion. The IPR contested the decision, and the later court judgment rejected the main allegations, but the dispute contributed to the institute’s institutional decline.
1952
Senate Internal Security Subcommittee investigation
A Senate investigation reviewed roughly 20,000 documents and questioned IPR personnel. Its report characterized the institute as vulnerable to Communist influence and alleged that it had helped disseminate information favorable to Communist objectives. These conclusions remained politically influential but were disputed and should not be treated as proof of collective organizational control.
1950
Postwar allegations of Communist influence
Critics led by Alfred Kohlberg alleged that Communist sympathizers had influenced IPR personnel, publications, and policy discussions. The controversy grew through the organization’s association with Amerasia and through accusations involving several former associates.
Brand decisions
1955
