T. V. Soong
In 1936, Wang clashed with Chiang over foreign policy. In an ironic role reversal, the left-wing "progressive" Wang argued for accepting the German-Japanese offer of having China sign the Anti-Comintern Pact while the right-wing "reactionary" Chiang wanted a rapprochement with the Soviet Union. During the 1936 Xi'an Incident, in which Chiang was taken prisoner by his own general, Zhang Xueliang, Wang favored sending a "punitive expedition" to attack Zhang. He was apparently ready to march on Zhang, but Chiang's wife, Soong Mei-ling, and brother-in-law, T. V. Soong, feared that such an action would lead to Chiang's death and his replacement by Wang, so they successfully opposed this action.
