TAIPEI - Taiwan swore in Tsai Ing-wen as its first female president Friday ahead of a grand ceremony celebrating the island's unique identity, likely to raise hackles in Beijing as ties with China rapidly cool.
Tsai took office after winning a landslide victory in January to defeat the ruling Kuomintang, ending an eight-year rapprochement with Beijing under outgoing president Ma Ying-jeou.
Voters felt Ma had moved too close to China, which still sees self-ruling Taiwan as part of its territory awaiting reunification.
Beijing-sceptic Tsai swept in with a campaign to restore Taiwanese pride, a message that resonated with a public tired of living in China's shadow.
As 20,000 invited guests and cheering members of the public watched outside the presidential office, Tsai raised her right arm as she read the oath in front of Taiwan's national flag.
She received the seal of the Republic of China - Taiwan's official name - and the presidential seal.
Tsai then accompanied Ma out of the presidential office as he shook hands with smiling staff and a brass marching band paraded.
" Tsai Ing-wen is the first woman president in Taiwan's history so I want to witness this sacred moment," said teacher Chen Su-mei, 48, who watched the swearing in on a big screen outside the presidential office.
"I hope she will bring more stability to Taiwan and revive our economy. We have high hopes for her." The Taiwan-centric inauguration celebrations will include 1,000 performers in a showcase of the island's history and culture, entitled "Pride of Taiwan".
Mock protesters will appear alongside singers in a "March of Taiwan Democracy" segment, billed as a performance to remind the new government to listen to the public.
Choirs will also perform "Ilha Formosa", a poetic tribute to Taiwan banned in 1979, when the KMT ruled under martial law, because it had been adopted as an anthem by opposition groups.
But the element of proceedings most closely watched - particularly by Beijing - will be Tsai's 30-minute inauguration speech.
Beijing wants Tsai to publicly acknowledge its message that there is only "one China", a concept enshrined in a tacit agreement with the KMT known as the "1992 consensus".
Recognition of that agreement formed the bedrock of the thaw under Ma, but Tsai and her Democratic Progressive Party have never backed it.
Tsai has pledged to maintain the "status quo" with Beijing, but observers say she is highly unlikely to show any sign of compromise on the "one China" issue during her speech.
" Tsai has said repeatedly cross-strait ties will be based on democratic principle and Taiwan's public opinion, so it would be difficult for her to say the things China wants to hear," said Lai I-chung, deputy director of Taiwan Thinktank and a former director of the DPP's China affairs division.
Voters will instead want to hear how Tsai will revive Taiwan's flagging economy and be reassured the island's sovereignty will remain secure.
The vast majority of Taiwanese want peaceful relations with China, but not at the expense of their cherished democratic culture.
"She can negotiate with China as long as Taiwan's sovereignty is upheld," 19-year-old college student Hu Hsiu-chi told AFP.
"To me Taiwan is an independent country." Taiwan split from the mainland in 1949 after a civil war but has never declared a breakaway.
Beijing has warned Tsai against any move towards formal independence - the DPP is traditionally a pro-independence party.
Chinese pressure tactics in recent months have included the deportation of Taiwanese fraud suspects to the mainland from Kenya and Malaysia, infuriating Taipei.
