反分裂國家法
The PRC passed an Anti-Secession Law shortly before Lien's trip. While the Pan-Green Coalition held mass rallies to protest the codification of using military force to retake Taiwan, the Pan-Blue Coalition was largely silent. The language of the Anti-Secession Law was clearly directed at the independence supporters in Taiwan (termed "'Taiwan independence' secessionist forces" in the law) and designed to be somewhat acceptable to the Pan-Blue Coalition. It did not explicitly declare Taiwan to be part of the People's Republic of China but instead used the term "China" on its own, allowing definitional flexibility. It made repeated emphasis of "promoting peaceful national unification" but left out the concept of "one country, two systems" and called for negotiations in "steps and phases and with flexible and varied modalities" in recognition of the concept of eventual rather than immediate incorporation of Taiwan. In 2020, Li Keqiang left out the word "peaceful" when referring to unification with Taiwan, indicating a possible policy shift.
