War of 2020

The War of 2020 is a fictional conflict depicted in Battlefield 4 and its expansion packs between the United States of America, the People's Republic of China, and the Russian Federation.

Background
Admiral Chang Wei was a high ranking official in the People's Republic of China and political rival to Jin Jié. Having essentially lost the election, Chang set out to orchestrate a coup d'etat to assassinate Jié, which would then be blamed on the United States, in order to assume power. Before his plans could be enacted, however, CIA agent Laszlo Kovic discovered the coup when looking for answers as to who had set up his unit at the Chinese/North Korean border.

Course of Events
After having been declared the future leader of China, Jié's bodyguard, Chinese Secret Service agent Huang "Hannah" Shuyi took him to her village to meet her family and help spread his word of hope. Later that night, Chang sent Chinese special operatives to the village to assassinate Jié and all possible witnesses. Miraculously, Jié and Hannah made it out alive, but at the cost of Hannah's entire village.

With Jié believed to have been killed, Chang announced Jié's assassination was at the hands of the United States. He then declared martial law and sought the support of Russia, whom was more than willing to comply, due to the events of the War of 2014.

Chang promptly ordered the assault on all nearby warships within the South China Sea. The USS Titan was one such ship that had been attacked and severely damaged by PLA forces.

Meanwhile, Jin Jié and Hannah went into hiding in Shanghai, where Agent Kovic was ordered to protect them. Tombstone was ordered on a covert mission to safely extract the three to safety aboard the USS Valkyrie. While successful, Tombstone were left unaware of the true identities of Jié and Hannah. Before returning to the Valkyrie themselves, Tombstone herded a large group of refugees that had been stranded in the Shanghai bay due to an EMP blast toward the Valkyrie. Captain Garrison then set course for the nearby USS Titan which would have been able to accommodate the refugees.

Upon arriving at the Titan, the result of Chang's attacks is soon apparent. After neutralizing all enemy forces, the Valkyrie then sets a course for Singapore.

Multiplayer
In Battlefield 4's multiplayer, the US, China, and Russia continue the fight in several regions across the world, including many parts of China, Paris, the Middle East, and Russia.
