Lennart Petri

Carl Johan Lennart Petri (10 May 1914 – 25 June 1996) was a Swedish diplomat. Petri began his diplomatic career in 1938 and served in various international postings, including Madrid, Washington, Buenos Aires, and Bogotá, with a focus on supporting Swedish exports. After returning to Stockholm, he worked on major credit agreements with the Soviet Union and later served in key roles in Paris and Moscow, where he challenged pro-Soviet leanings within the Swedish delegation. He was appointed ambassador to Rabat, Tunis, and Tripoli in the late 1950s and later served as ambassador to Beijing and Phnom Penh during the turbulent Vietnam War years. Petri criticized Sweden’s Vietnam policy as naïve and driven by poor judgment, attributing its failures to Foreign Minister Torsten Nilsson and his inner circle. Known for his independence and bluntness, Petri often clashed with political leadership over foreign policy direction. He concluded his diplomatic career with postings in Vienna and Madrid, where he again resisted prevailing political assumptions—this time regarding Spain’s transition to democracy. After retiring in 1980, he served as a foreign policy advisor and published his memoirs in 1996, offering reflections on decades of global political change.
