On the evening of May 17, the PSC met at Zhongnanhai to finalize plans for martial law. At the meeting, Zhao announced that he was ready to "take leave", citing he could not bring himself to carry out martial law. The elders in attendance at the meeting, Bo Yibo and Yang Shangkun, urged the PSC to follow Deng's orders. Zhao did not consider the inconclusive PSC vote to have legally binding implications for martial law; Yang Shangkun, in his capacity as Vice Chairman of the Central Military Commission, mobilized the military to move into the capital.
