How did the Treaty of Shimonoseki affect Japanese access to Chongqing?

The Treaty of Shimonoseki, signed in 1895 following the first Sino-Japanese War, significantly expanded Japanese access to Chongqing.12

While the city had been opened to British trade in 1890, the treaty formally granted Japan the right to access the wharves of Chongqing. This provision facilitated the establishment of a Japanese concession at Wangjiatuo, located on the south shore of the Yangtze River, which was formally opened in 1901. This concession remained in place until 1937, when it was abandoned by Japan at the start of the second Sino-Japanese War.2
