Greece and China
China and Greece are mutually dependent on each other in certain key areas for significant reasons: Greece provides two dock terminals at Piraeus for China's COSCO China Ocean Shipping Company, Piraeus being a classic front door entrance to Europe for trade, and this $3.5 billion USD (and counting) investment has grown Piraeus to be the second largest port in the Mediterranean.
For Greece, Chinese investment in infrastructure (particularly in Piraeus) gives Hellas not just money, but technological advancement. Greece already has an important interest in shipping, but the success of China's billion dollar investment in Pireaus beginning in 2009 has continued with a new 2019 proposal for a $880 million USD investment (see Xihuanet) in expanding Pireaus piers.
Currently COSCO is paying $100 million USD per year on a 35-year lease for docks 2 and 3.
Both the former Greek Premier Tsipras and the current PM Greek Prime Minister Kyriakos Mitsotakis are dedicated to the China-Greek relationship. Tsipras had to fight significant opposition within his own SYRIZA party (and Greek unions in general) to keep the COSCO-Greek deal moving, and Mitsotakis has picked up the project without any change in attitude: the Chinese seem to be happy as is the Greek government.
The chief competition (in size) for the Chinese/Greek effort in Pireaus are the huge Mediterranean ports in the Spanish port of Algeciras, and Tanger Med in Morroco, which is a mutual effort by Danish, German and Moroccan companies.
