Taiwan's newly inaugurated president William Lai has called on China to stop threatening the island and accept the existence of its democracy.
He urged Beijing to replace confrontation with dialogue, shortly after being sworn in on Monday.
He also said Taiwan would never back down in the face of intimidation from China, which has long claimed the island as its own.
Mr Lai is loathed by China which sees him as a "secessionist".
It has also ramped up pressure on Taiwan in recent years.
Military incursions by China around the island's waters and airspace have become a routine affair in the past few years, triggering fears of conflict. In his speech, Mr Lai called this the "greatest strategic challenge to global peace and stability".
But the 64-year-old also stuck closely to the formula used by his predecessor president Tsai Ing-wen, whose legacy will be defined by her cautious but steady handling of Beijing.
Mr Lai, a doctor turned politician, won a three-way presidential race in January, securing an unprecedented third term for his Democratic Progressive Party (DPP). He had served as Ms Tsai's vice-president since 2020, and before that as her premier. In his younger days, he was known to be a more radical politician who openly called for Taiwanese independence, which has not escaped Beijing. It labelled him a "troublemaker" ahead of the polls, and Chinese state media even suggested he should be prosecuted for secession.
The Chinese government is yet to issue a statement on Mr Lai's inauguration. However, the Chinese embassy in the UK held a press briefing over the weekend, asking the UK government to not endorse it. And earlier last week, a spokesperson for China's Taiwan Affairs Office warned that the island's new leader "must seriously" consider the question of whether he wants peaceful development or confrontation.
And just as Mr Lai was being sworn in, China's Commerce Ministry announced sanctions against several US companies "involved in arms sales to Taiwan".
But on Monday, Mr Lai struck a far more conciliatory note. He reiterated he would not do anything to change the status quo - an ambiguous diplomatic status, which doesn't recognise Taiwan as a country despite its constitution and sovereign government. China insists on this and accuses major Taiwan allies such as the US of altering this delicate agreement by supporting the island.
Vowing peace and stability, Mr Lai also said he would like to see a re-opening of exchanges across the Taiwan straits including Chinese tourist groups coming to Taiwan. But he said people on the island must not be under any illusion about the threat from China and that Taiwan must further strengthen its defences.
This too was a continuation of Tsai's policy. Taiwan's former president believed that strengthening defence and earning the support of key allies such as the US and Japan was key to deterring China's plans of invasion. Her biggest critics say this military investment risks provoking China, making Taiwan even more vulnerable.
Nevertheless, yearly defence spending increased up to about $20bn (£16bn) under Ms Tsai, and Mr Lai has pledged even more funds. Taiwan has purchased new battle tanks, upgraded its fleet of F-16 fighter jets and bought new ones, and has built and launched a fleet of new missile ships to patrol the 100-mile Taiwan strait. Last September came the completion of what Ms Tsai considers the crowning achievement of her military program: Taiwan's first indigenously developed submarine.
