In Sino-Russian relations, the presence of the Guangdong–Hong Kong−Macao Greater Bay Area (GBA) plays a crucial role. Historically, exchange and co-operation between Russia and the GBA date back to 400 years ago, and can be divided into three phases: Qing–Tsarist Period, Revolutionary Period, and China–Soviet Period. While currently, new exchanges between Russia and the GBA are also developing, ranging from politics, military, economy, culture, aspects like education, religion, and media are also important. Under the Belt and Road Initiative (BRI) and the post-pandemic era, co-operation between the GBA and Russia is expected to be further developed.
