Some of Shanghai's buildings feature Soviet neoclassical architecture or Stalinist architecture, though the city has fewer such structures than Beijing. These buildings were mostly erected between the founding of the People's Republic in 1949 and the Sino-Soviet Split in the late 1960s. During this time period, large numbers of Soviet experts, including architects, poured into China to aid the country in the construction of a communist state. An example of Soviet neoclassical architecture in Shanghai is the modern-day Shanghai Exhibition Center.
