Pan-Green Coalition in the context of "Taiwan Solidarity Union"

The Kuomintang (KMT) is a major political party in the Republic of China (Taiwan). It was the sole ruling party of the country during its rule from 1927 to 1949 in Mainland China until its relocation to Taiwan, and in Taiwan ruled under martial law until 1987. The KMT is a centre-right to right-wing party and the largest in the Pan-Blue Coalition, one of the two main political groups in Taiwan. Its primary rival is the Democratic Progressive Party (DPP), the largest party in the Pan-Green Coalition. As of 2025, the KMT is the largest single party in the Legislative Yuan and is chaired by Cheng Li-wun.

The party was founded by Sun Yat-sen in 1894 in Honolulu, Hawaii, as the Revive China Society. He reformed the party in 1919 in the Shanghai French Concession under its current name. From 1926 to 1928, the KMT under Chiang Kai-shek successfully unified China in the Northern Expedition against regional warlords, leading to the fall of the Beiyang government. After initially allying with the Chinese Communist Party (CCP) in the First United Front, the party under Chiang purged communist members. It was the sole ruling party of China from 1928 to 1949 but gradually lost control while fighting the Empire of Japan in the Second Sino-Japanese War and the CCP in the Chinese Civil War. In December 1949, the Kuomintang retreated to Taiwan following its defeat by the communists.

The Pan-Blue Coalition, Pan-Blue force, or Pan-Blue group is a political coalition in the Republic of China (Taiwan) consisting of the Kuomintang (KMT), the People First Party (PFP), the New Party (CNP), the Non-Partisan Solidarity Union (NPSU), and the Young China Party (YCP). The name comes from the party color of the Kuomintang.

Regarding the political status of Taiwan, the coalition primarily maintains that the Republic of China instead of the People's Republic of China is the legitimate government of China. It also favors a Chinese and Taiwanese dual identity over an exclusive Taiwanese identity and backs greater friendly exchange with mainland China, as opposed to the Pan-Green Coalition which opposes Chinese identity in Taiwan.

The Democratic Progressive Party (DPP) is a centre-left Taiwanese nationalist political party in Taiwan. As the dominant party in the Pan-Green Coalition, one of the two main political camps in Taiwan, the DPP is currently the ruling party in Taiwan, leading a minority government that controls the presidency and the central government.

Founded in 1986 by Hsu Hsin-liang, Roger Hsieh and Lin Shui-chuan, a year prior to the end of martial law, the DPP is one of two major parties in Taiwan, the other being the Kuomintang (KMT), a Chinese nationalist party previously ruling the country as a one-party state, and its smaller allies in the Pan-Blue Coalition. It has traditionally been associated with a strong advocacy of human rights, emerging against the authoritarian White Terror that was initiated by the KMT, as well as the promotion of Taiwanese nationalism and identity. Lai Ching-te is the current chairperson of the DPP from 2023, who also serves as the incumbent President and is the third member of the DPP to hold the presidency; he succeeded fellow DPP member Tsai Ing-wen in May 2024.

Green Party Taiwan is a political party in Taiwan established on 25 January 1996. Although the party is sympathetic to Taiwanese nationalism and shares a number of centre-left positions with the Pan-Green Coalition, the party emphasizes campaigning primarily on social and environmental issues. The party is not a member of, and should not be confused with, the Pan-Green Coalition. Green Party Taiwan is a member of the Asia Pacific Greens Federation and participates in the Global Greens.

Much of the 400-strong membership are affiliated with the non-governmental organisation sector of Taiwanese society, as well as from academia and the youth community.

The New Power Party (NPP) is a political party in Taiwan formed in early 2015. The party emerged from the Sunflower Student Movement in 2014, and advocates for universal human rights, civil and political liberties, as well as Taiwan independence/nationalism. The party is a part of the political phenomenon known as the "Third Force" (第三勢力), in which new political parties, unaligned with traditional Pan-Green or Pan-Blue Coalitions, sought to provide an alternative in Taiwanese politics. Nevertheless, the NPP's policies are very much aligned with and closely match the Pan-Green camp; thus the NPP cooperated with the Democratic Progressive Party (DPP) against the Kuomintang (KMT) in the 2016 elections, going as far as not to run in traditional KMT strongholds to avoid competition with the DPP. The party works in tandem with a perceived generational shift towards Taiwan-centrism as the new socio-cultural norm.

The party was started by Freddy Lim, lead vocalist of Taiwanese heavy metal band Chthonic, veteran activist Michael Lin, human rights lawyers Lin Feng-cheng [zh], Chiu Hsien-chih, and other prominent figures of the Sunflower Student Movement. Lim headed the party-building process, which saw the inclusion of Hung Tzu-yung, sister of the late Hung Chung-chiu, environmental lawyer Ko Shao-chen [zh], and author-activist Neil Peng into the party. On 12 September 2015, the NPP was officially formed with the election of Huang Kuo-chang as executive leader, heading a leadership team of six deputy leaders.
