 On January 30, Chiang Kai-shek decided to temporarily relocate the capital from Nanjing to Luoyang as an emergency measure, due to the fact that Nanjing's proximity to Shanghai could make it a target.Because Shanghai was a metropolitan city with many foreign interests invested in it, other countries, such as the United States, the United Kingdom and France, attempted to negotiate a ceasefire between Japan and China.However, Japan refused, instead continuing to mobilize troops in the region.
