The Sino-Soviet split was the gradual worsening of relations between the People's Republic of China (PRC) and the Union of Soviet Socialist Republics (USSR) during the Cold War. This was primarily caused by doctrinal divergences that arose from their different interpretations and practical applications of Marxism–Leninism, as influenced by their respective geopolitics during the Cold War of 1947–1991. In the late 1950s and early 1960s, Sino-Soviet debates about the interpretation of orthodox Marxism became specific disputes about the Soviet Union's policies of national de-Stalinization and international peaceful coexistence with the Western Bloc, which Chinese leader Mao Zedong decried as revisionism. Against that ideological background, China took a belligerent stance towards the Western world, and publicly rejected the Soviet Union's policy of peaceful coexistence between the Western Bloc and Eastern Bloc. In addition, Beijing resented the Soviet Union's growing ties with India due to factors such as the Sino-Indian border dispute, and Moscow feared that Mao was too nonchalant about the horrors of nuclear warfare.

Tunnel warfare is using tunnels and other underground cavities in war. It often includes the construction of underground facilities in order to attack or defend, and the use of existing natural caves and artificial underground facilities for military purposes. Tunnels can be used to undermine fortifications and slip into enemy territory for a surprise attack, while it can strengthen a defense by creating the possibility of ambush, counterattack and the ability to transfer troops from one portion of the battleground to another unseen and protected. Also, tunnels can serve as shelter from enemy attack.

The People's Liberation Army Navy Submarine Force (PLANSF) is the submarine service of the People's Liberation Army Navy. It consists of all types of submarines in operational service organized into three fleets: the North Sea Fleet, the East Sea Fleet, and the South Sea Fleet. Submarines have long been one of the three focuses of the People's Liberation Army Navy, and when the decision was made in late 2006 to concentrate on building other principal surface combatants to strengthen the air defense and to further delay the construction of aircraft carriers due to insufficient air cover, submarines will continue to play the lead dominant role in the assault force for the PLAN. Currently, PLANSF operates a fleet of 66 submarines which include nuclear as well as conventional submarines.
