The Communications Clique (Chinese: 交通系; pinyin: jiaotongxi) was a powerful interest group of politicians, bureaucrats, technocrats, businessmen, engineers, and labour unionists in China's Beiyang government (1912-1928). It is also known as the Cantonese Clique because many of its leaders hailed from Guangdong. They were named after the Ministry of Posts and Communications which was responsible for railways, postal delivery, shipping, and telephones as well as the Bank of Communications. This ministry earned five times more revenue for the government than all the other ministries combined.
