Gathering momentum

The hunger strikes galvanized support for the students and aroused sympathy across the country. Around a million Beijing residents from all walks of life demonstrated in solidarity from 17 to 18 May. These included PLA personnel, police officers, and lower party officials. Many grassroots Party and Youth League organizations, as well as government-sponsored labor unions, encouraged their membership to demonstrate. In addition, several of China's non-Communist parties sent a letter to Li Peng to support the students. The Chinese Red Cross issued a special notice and sent in many personnel to provide medical services to the hunger strikers on the square. After the departure of Mikhail Gorbachev, many foreign journalists remained in the Chinese capital to cover the protests, shining an international spotlight on the movement. Western governments urged Beijing to exercise restraint.

The movement, on the wane at the end of April, now regained momentum. By 17 May, as students from across the country poured into the capital to join the movement, protests of various sizes occurred in some 400 Chinese cities. Students demonstrated at provincial party headquarters in Fujian, Hubei, and Xinjiang. Without a clearly articulated official position from the Beijing leadership, local authorities did not know how to respond. Because the demonstrations now included a wide array of social groups, each having its own set of grievances, it became increasingly unclear with whom the government should negotiate and what the demands were. The government, still split on how to deal with the movement, saw its authority and legitimacy gradually erode as the hunger strikers took the limelight and gained widespread sympathy. These combined circumstances put immense pressure on the authorities to act, and martial law was discussed as an appropriate response.

The situation seemed intractable, and the weight of taking decisive action fell on paramount leader Deng Xiaoping. Matters came to a head on 17 May during a Politburo Standing Committee meeting at Deng's residence. At the meeting, Zhao Ziyang's concessions-based strategy, which called for the retraction of the 26 April Editorial, was thoroughly criticized. Li Peng, Yao Yilin, and Deng asserted that by making a conciliatory speech to the Asian Development Bank, on 4 May, Zhao had exposed divisions within the top leadership and emboldened the students. Deng warned that "there is no way to back down now without the situation spiraling out of control", and so "the decision is to move troops into Beijing to declare martial law " as a show of the government's no-tolerance stance. To justify martial law, the demonstrators were described as tools of " bourgeois liberalism " advocates who were pulling strings behind the scenes, as well as tools of elements within the party who wished to further their personal ambitions. For the rest of his life, Zhao Ziyang maintained that the decision was ultimately in Deng's hands: among the five PSC members present at the meeting, he and Hu Qili opposed the imposition of martial law, Li Peng and Yao Yilin firmly supported it, and Qiao Shi remained carefully neutral and noncommittal. Deng appointed the latter three to carry out the decision.

On the evening of 17 May, 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.

Li Peng met with students for the first time on 18 May in an attempt to placate public concern over the hunger strike. During the talks, student leaders again demanded that the government rescind the 26 April Editorial and affirm the student movement as "patriotic". Li Peng said the government's main concern was sending the hunger strikers to hospitals. The discussions were confrontational and yielded little substantive progress, but gained student leaders prominent airtime on national television. By this point, those calling for the overthrow of the party and Li Peng and Deng became prominent both in Beijing and in other cities.

In the early morning of 19 May, Zhao Ziyang went to Tiananmen in what became his political swan song. He was accompanied by Wen Jiabao. Li Peng also went to the square but left shortly thereafter. At 4:50 am Zhao made a speech with a bullhorn to a crowd of students, urging them to end the hunger strike. He told the students that they were still young and urged them to stay healthy and not to sacrifice themselves without due concern for their futures. Zhao's emotional speech was applauded by some students. It would be his last public appearance.

Students, we came too late. We are sorry. You talk about us, criticize us, it is all necessary. The reason that I came here is not to ask you to forgive us. All I want to say is that students are getting very weak. It is the 7th day since you went on a hunger strike. You can't continue like this. You are still young, there are still many days yet to come, you must live healthily, and see the day when China accomplishes the Four Modernizations. You are not like us. We are already old. It doesn't matter to us anymore.

— Zhao Ziyang at Tiananmen Square, 19 May 1989
