The Sunflower Movement (Chinese: 太陽花學運; Pinyin: Tàiyáng huā xué yùn) was a student-led protest in 2014 against the Cross-Strait Economic Cooperation Framework Agreement, initiated by the Ma Ying-jeou administration with the purpose of institutionalising trade and transactions between the ROC and the PRC. The agreement sparked a massive controversy, as many feared that increased economic dependence on the Mainland will make Taiwan more vulnerable to potential threats and sanctions by China, and since the negotiations were being held in secret, the extent of the cooperation would not be revealed in advance.
Protesters occupied the Legislative Yuan building between mid-March and mid-April, and demanded the government carefully reconsider the trade agreement.
Though the students represented political views associated with the pan-Green coalition, their movement was not organised by the DPP.
