China is a country comprising a large part of the mid-eastern region of Asia, and one of the largest countries in the world.
In the 1220s, the Assassins Altaïr Ibn-La'Ahad, his wife Maria and his son Darim Ibn-La'Ahad had traveled to China, then partly under Mongol control, to assassinate the Mongol leader Genghis Khan. They liaised with Qulan Gal, a Mongol Assassin, and designed plans to end the Mongol leader's life.
In 1227, Altaïr and Qulan Gal infiltrated Genghis Khan's tent in Xingging, near Xia Province, though Altaïr was spotted and wounded by a Mongol soldier. Qulan Gal was able to kill the soldier and bring Altaïr to safety, after which Genghis Khan tried to escape by horse. Qulan Gal shot the Khan's horse with an arrow, causing him to fall. Right afterwards, Darim killed the Khan with another arrow.
By the late 1300s, the Chinese Assassins based themselves in the city of Beijing, and were led by Fang Xiaoru. In 1402, China fell under the control of the Templar emperor Yongle, who had thousands of suspected Assassins across the country arrested and executed; including Fang Xiaoru. Li Tong, a female Assassin whose parents had also been killed during the purge, was able to escape Beijing with an apprentice and an Apple of Eden.
By 1524, the Emperor Jiajing had succeeded where Yongle failed, eradicating the Chinese Assassins. The Mentor and his apprentice Shao Jun fled to Italy to seek aid. Jiajing's henchmen found and killed Jun's Mentor, but the retired, former Italian Mentor Ezio Auditore da Firenze gave her refuge and advice. After killing her pursuers, an empowered Jun journeyed home to rebuild the Chinese Order.
In 2012, the Templars were planning to launch a satellite into space with a Piece of Eden attached to it. The Assassins listed China as one of the possible countries where the satellite was located.
