University named after Andrei Zhdanov (now Saint Petersburg State University) in 1970 and graduated in 1975. His thesis was on "The Most Favored Nation Trading Principle in International Law". While there, he was required to join the Communist Party of the Soviet Union (CPSU); he would remain a member until it ceased to exist in 1991. Putin met Anatoly Sobchak, an assistant professor who taught business law, and who later became the co-author of the Russian constitution and of corruption schemes in France. Putin would be influential in Sobchak's career in Saint Petersburg, and Sobchak would be influential in Putin's career in Moscow. In 1997, he received his Ph.D. in economics (Candidate of Economic Sciences) at the Saint Petersburg Mining University for a thesis on the strategic planning of the mineral economy. KGB career In 1975, Putin joined the KGB and trained at the 401st KGB School in Okhta, Leningrad. After training, he worked in the Second Chief Directorate (counterintelligence), before he was transferred to the First Chief Directorate, where he monitored foreigners and consular officials in Leningrad. In September 1984, Putin was sent to Moscow for further training at the Yuri Andropov Red Banner Institute. Multiple reports have suggested Putin was sent by the KGB to New Zealand, corroborated through New Zealand eyewitness accounts and government records. This has never been confirmed by Russian security services. Former Waitākere City mayor Bob Harvey and former Prime Minister David Lange alleged that Putin served in Wellington and Auckland. He allegedly worked for some time undercover as a Bata shoe salesman in central Wellington. From 1985 to 1990, he served in Dresden, East Germany, using a cover identity as a translator. "Putin and his colleagues were reduced mainly to collecting press clippings, thus contributing to the mountains of useless information produced by the KGB", Russian-American Masha Gessen wrote in their 2012 biography of Putin. His work was also downplayed by former Stasi spy chief Markus Wolf and Putin's former KGB colleague Vladimir Usoltsev. Journalist Catherine Belton wrote in 2020 that this downplaying was actually cover for Putin's involvement in KGB coordination and support for the terrorist Red Army Faction, whose members frequently hid in East Germany with the support of the Stasi. Dresden was preferred as a "marginal" town with only a small presence of Western intelligence services. According to an anonymous source, a former RAF member, at one of these meetings
