Hsiao Ch'ien was born into a sinicized Mongolian family in Beijing, China, in 1910. His father died before his birth and his mother died when he was seven. In 1931, he enrolled at Furen University where he and a young American named William Allen founded the English magazine China in Brief. In 1933, he entered the Faculty of English at Yenching University but switched to the Faculty of Journalism later that year before graduating in 1936.

In 1939, just before the Second World War broke out, he travelled to England to teach Chinese at the School of Oriental and African Studies and serve as a foreign correspondent for Takung Pao. After the outbreak of war, he also served as a war correspondent. SOAS relocated to Cambridge during the Second World War so, after spending one night in London, Hsiao Ch'ien went to Cambridge. He was classified as an 'enemy alien' by the Home Office but this changed after the Japanese bombed Pearl Harbor and the Chinese became members of the grand alliance.

The BBC chose Hsiao Ch'ien to report back to China about the European war and the war effort of the English. Around this time, he became good friends with Mulk Raj Anand and supported the Indian call for independence. He voiced his support for the Indian cause in his weekly BBC broadcast but the censors deleted it before it went on air. Later George Orwell, who was head of the BBC's Far Eastern Division, invited him to do several special broadcasts to the Indians and Americans, but strictly on the subject of literature.

SOAS moved back to London in July 1940 and Ch'ien took up residence in a house that catered especially to Asians; he shared the ground floor flat with a Tamil named Rajarantu, who later became the first deputy premier and foreign minister of Singapore. In wartime London, Hsiao Ch'ien socialized with Bloomsbury Group affiliates like Bertrand Russell, Leonard Woolf and E. M. Forster, with whom he became close friends. According to his autobiography, he first met Forster at the PEN Club memorial meeting for Rabindranath Tagore held on 9 May 1941. However, according to India Office files, this meeting was hosted by Krishna Menon and the India League. The speakers were Edward Thompson, Hewlett Johnson (Dean of Canterbury), Nagendranath Gangulee (Tagore's nephew), Beatrix Lehmann (actress), Bhicoo Batlivala, Helen Kirkpatrick (Chicago Daily Tribune) and M. Maisky (Soviet ambassador). Other attendees included Mulk Raj Anand, Tahmankar, Sunder Kabadia, Krishnarao Shelvankar, Alagu Subramanian, Iqbal Singh, Sasadhar Sinha and Asha Bhattacharya led the singing of Tagore's songs.

In June 1944, Hsiao Ch'ien became a journalist for Dagongbao and set up an office in Fleet Street, London. Soon afterwards he was sent to France and other parts of Western Europe as a war correspondent; he covered the meeting of the United Nations in San Francisco, and attended the Potsdam Conference in July 1945.

Hsiao Ch'ien returned to Shanghai in 1946 and took up writing. He was considered right-wing by the Chinese government and banished to the countryside but later received redress. He died in 1999 in Beijing.

A Sri Lankan Tamil from an affluent English-speaking Roman Catholic family, M. J. Tambimuttu arrived in Britain at the age of 22. Having already published three volumes of poetry in Ceylon, he soon immersed himself in the literary world of London’s Soho and Fitzrovia. Within little more than a year of his arrival he had founded the magazine Poetry London (1939–51) with the writer and musician Anthony Dickins. While Dickins' involvement quickly diminished, Tambimuttu edited the first fourteen volumes of the magazine and a number of books, as well as writing his own poetry. In July 1943, with the backing of publishers Nicholson and Watson (on the recommendation of T. S. Eliot who was an admirer of his), he established Editions Poetry London, which published contemporary verse and prose, as well as art books, in hard cover. Tambimuttu was also a regular participant in the BBC radio series Talking to India during the Second World War. A man of charisma as well as a talented editor, he had an array of friends and acquaintances with whom he enjoyed the pubs and cafes of Fitzrovia.

Tambimuttu returned to Sri Lanka in 1949 then moved to New York in 1952 where he launched the magazine Poetry London–New York (1956–60) as well as continuing to publish short fiction and poetry of his own, and lecturing at the Poetry Center and New York University. In 1968 he returned to London where he founded a final magazine, Poetry London/Apple Magazine, which had just two issues, and a publishing company, the Lyrebird Press. He died of heart failure in London in 1983.
