China

China was the main enemy of the United States during the Great War (it seems USA had correct political relations with the Soviet Union).
 * The president of China in 2073, and probably until 2077 was called Xin.
 * China capital was Beijing.
 * The only mention of China being communist in any of the Fallout games is in the dialogue with Enclave of United States President Dick Richardson, who calls the Chinese "damn Reds" (however Horrigan hates "red mutants"). It also mentioned as such in Fallout Bible Timeline and van Buren tech demo.

It is unknown exactly what kind of political structure the Chinese adhered to. It can be assumed that China as some kind of communist country suits the Fallout setting best, however. Talking about China political system it could be so called communism or market communism like nowadays (2007 year). Keeping it short it means:
 * communist party dictatorship (about 50-60 milion members - c.a. 5% of population),
 * limited free market economy, benefiting mostly for communist party members and their affiliates,
 * most part of population socialy excluded (particulary peasants on a province).

China shows up in Fallout's history notes as the biggest competitor of the United States, not just in military, but likely also economically and scientifically as they attempted to be the first to drill the last oil resource in the world. It is implied that Americans sabotages this attempt and that without such sabotage the Chinese would've been first. The Chinese also try to keep pace on power armor developments, though how much they managed this is unknown.

It is a known fact that China invaded Alaska, though it is disputed in which year (Fallout Bible: 2059 or 2066, Sierra Depot: 2077), but the exact details on China as a nuclear power are sketchy at best. It is not actually known how much nuclear power China brought to the final blasts of the Great War or even if it was the only country (or even one of the countries?) throwing bombs at the United States, who was at that time in dispute with many countries.

According to Fallout Bible timeline in June 2276 China supply lines from the nations China has annexed begin to break down (notice: nowadays directly neighbouring states are: Northern Korea, Russia and Kazakstan/former Soviet Union, Mongolia, India, Bhutan, Nepal, Burma/Myanmar, Laos, Vietnam and through Taiwan Strait - Republic of China; there are some asian countries with significant chinese population also, eg. Singapore or Malaysia).

Incursion to Hoover Dam
Shortly before the big war started, a Chinese infiltration and sabotage team discovered the Hoover Dam secret genetics laboratory (Classified Sub-Level 1C) and tried to destroy Hoover Dam, so the genetic work could never be used against them. Some of the Chinese stealth soldiers made it into Sub-level 1C, while others were planting bombs in the main generator rooms (Scum Pits). One of the bombs went off prematurely and alerted all of Hoover Dam, including the guards in S1C. Things become cloudy in the reports due to the chaos that ensued, but suffice it to say that the Chinese were defeated, the generators were heavily damaged, and S1C was compromised. A couple of Chinese stealth solders and four scientists were trapped in S1C after the hatch was sealed. The Prisoner can find this soldiers there and use the materials from their stealth armor to make own armor (Hei Gui armor as possible part of equipment is confirmed by one if van Buren screenshots also).

Chinese weapons

 * The Chinese solution to invasion by U.S. forces in power armor was its Hei Gui stealth armor, worn by elite Chinese "Black Ghost" counterinsurgency/terror units.


 * MEC Gauss MiniGun was developed by Chinese.


 * Chinese Assault Rifle
