China

After the death of emperor Yuan Shikai in 1916, China fell into a state of disarray, warlords were rising up and taking control of land that previously belonged to the Republicans, eventually the republicans had re-gained a foothold on their sovereignty they controlled both Beijing and Nanjing which gave them the most legitimacy amongst the world. The leader of China was Sun-Yat Sen who was appointed presidency of the ROC not to long after, he one again reformed the political system of the ROC so that they would be an actual Republic.

Warlord Campaigns
China would remain in it’s warlord state until in August 1928 when Japan came to China in an attempt to continue to expand their influence they offered to help China deal with their warlord problem with the backing of JANZAC to help them, Japan also requested that Japan and their allies have top priority for trading, China accepted the deal and so the warlord campaigns began and would continue for the most part until October 1929. Toward the end of the campaign, mainly Japanese and Chinese forces were continuing the fight and had both cornered their final Warlord, the Fengtian warlord in Manchuria, the two sides moved in on Manchuria and for the first time since 1911 China was fully unified

After the end of the campaigns against the warlords in China, as a reward for helping China during the wars Japan demanded unrestricted access to China’s railway system for trade, China refused this deal and instead proposed that China becomes a fully fledged member of JANZAC so that China would regain a part of their sovereignty, the three original members agreed to their new member.
