Last updated August 31, 2026
Overview
Joint Publishing, also known as Sanlian Press or SDX Joint Publishing, is a Hong Kong bookstore chain and publishing business whose institutional origins date to the merger of three Shanghai-based cultural organizations in 1948. Life Bookstore, Reading Press, and New Knowledge Bookstore combined to form the organization commonly known in Chinese as Sanlian, a name that reflects the three-way union. The English abbreviation SDX derives from the initial letters of the three predecessor names in Chinese transliteration. The merged organization moved its headquarters to Beijing in March 1949 and established a Hong Kong-based subsidiary. Following the founding of the People's Republic of China later that year, the Hong Kong operation became an important channel for distributing and publishing material connected with mainland China, while the mainland organization was nationalized. The separation of the Hong Kong business from the mainland publishing structure became increasingly significant during the Cultural Revolution, when publishing activity in mainland China was severely disrupted. The Hong Kong operation survived in part by reissuing older works and maintaining a continuing publishing presence. After several relocations, the Hong Kong business settled at premises on Queen Victoria Street in May 1971. It opened a ground-floor retail outlet there in July 1974, strengthening its identity as both a publisher and a public-facing bookseller. In 1978, after the end of the Cultural Revolution and the beginning of China's reform period, the Hong Kong company began publishing books independently and entered arrangements with international publishers. Its editorial focus initially emphasized Chinese culture, literature, and art, later expanding toward Hong Kong subjects and social science. This combination of locally relevant publishing and specialist retail helped the chain expand its store network in Hong Kong. Joint Publishing also participated in mainland Chinese and overseas expansion. Mainland activities included joint ventures in several cities, while the international retail network at one stage included stores in Toronto, Vancouver, New York, Los Angeles, and San Francisco. These operations should not automatically be treated as the same corporate entities: mainland businesses using the Sanlian or Joint Publishing name, including SDX Joint Publishing and Shanghai Joint Publishing, developed under separate ownership and institutional arrangements. Shanghai Hong Kong Joint Publishing, established in 1999, was described as a joint venture involving the Hong Kong company, Shanghai Book, and Shanghai Joint Publishing. The Hong Kong business was incorporated as Joint Publishing (Hong Kong) Company Limited in January 1988. Today, Joint Publishing (Hong Kong) operates as a subsidiary of Sino United Publishing (Holdings) Limited and remains associated with book retailing, Chinese-language publishing, cultural titles, literature, arts, social-science works, and books concerning Hong Kong. Its position combines commercial bookstore operations with the distribution of Chinese-language cultural and educational material. The brand has also attracted public controversy: in March 2021, a Hong Kong High Court judgment found the company liable for defamation over published claims concerning alleged United States funding of opposition groups in Hong Kong.
History
Joint Publishing's roots lie in three Shanghai publishing and bookselling organizations: Life Bookstore, Reading Press, and New Knowledge Bookstore. Their merger on 18 October 1948 created the organization later known as Sanlian or SDX Joint Publishing. The merger consolidated publishing, bookselling, and cultural distribution activities under a shared identity that retained the memory of all three predecessors. The new organization moved its headquarters to Beijing in March 1949 and created a Hong Kong subsidiary. After the establishment of the People's Republic of China in October 1949, the mainland organization was nationalized, while the Hong Kong operation developed a distinct role. It became an outlet for mainland publications and a bridge for Chinese-language cultural material, but it was not identical to the later mainland companies that adopted the Sanlian or Joint Publishing name. The Cultural Revolution severely affected publishing in mainland China from 1966 onward. The Hong Kong operation continued, relying in part on the re-publication of older books. After the Cultural Revolution ended in 1976 and China's reform period began, the Hong Kong business changed direction. In 1978 it started producing books independently and working with international publishers. Its editorial emphasis developed from Chinese culture, literature, and art toward a broader program that included Hong Kong topics and social science. The business also expanded its physical retail presence. Following multiple relocations, it moved to its Queen Victoria Street premises in May 1971 and opened a retail shop on the ground floor in July 1974. The company subsequently opened additional Hong Kong branches. It also entered mainland Chinese markets through joint ventures and operated, at one stage, stores in Toronto, Vancouver, New York, Los Angeles, and San Francisco. In January 1988, the Hong Kong operation was registered as Joint Publishing (Hong Kong) Company Limited. A further corporate development came in October 1999, when Shanghai Hong Kong Joint Publishing was established as a joint venture involving Joint Publishing (Hong Kong), Shanghai Book, and Shanghai Joint Publishing. The latter entities belong to separate mainland institutional histories. SDX Joint Publishing became independent from the Hong Kong company in 1986 after its earlier relationship with the People's Publishing House, while Shanghai Joint Publishing was founded in 1986 as a subsidiary associated with Jiefang Daily. In the contemporary period, Joint Publishing (Hong Kong) operates under Sino United Publishing (Holdings) Limited. Its combined bookstore-and-publisher model gives it a role in retailing books and issuing or distributing publications, particularly Chinese-language works in cultural, literary, artistic, local-history, and social-science fields. The company also became involved in a significant legal controversy in 2021, when the Hong Kong High Court held it liable for defamation in relation to published claims about alleged foreign funding of Hong Kong opposition groups.
