Beijing: For Taiwan, it has been the best of weeks and the worst of weeks.
First it suffered its biggest diplomatic humiliation in a decade, shut out of the world's peak health summit in Geneva, at China's demand.
Yet just two days later, the island was exalted by the international community for breaking new ground in Asia as Taiwan's high court ruled in favour of same-sex marriage.
Both events came as Taiwan's President Tsai Ing-wen marked a year since her inauguration, and a seismic shift in Taiwan's politics.
For nine years under her predecessor Ma Ying-jeou, the Kuomintang (KMT) had built an economic bridge to China, allowing direct flights, tourism, and trade, but overreached and alienated young voters facing high unemployment.
In her inauguration speech as president, Ms Tsai - leader of the Democratic Progressive Party (DPP), which has traditionally leaned towards independence - had refused to acknowledge Beijing's core policy on cross-strait relations, the so-called 1992 Consensus that there is one China.
China froze official communication. The consequences are still flowing. Chinese tourist numbers to Taiwan fell 42 per cent in the first three months of 2017.
On Friday a former DPP employee, human rights activist Li Ming-che, became the first Taiwanese to be arrested in China on subversion charges. His wife, Li Ching-yu, said on Monday she is yet to be notified by the Chinese government, despite previous agreements between China and Taiwan that notification of a detention occur within 24 hours.
China has racheted up efforts to isolate Taiwan internationally.
After meeting Chinese President Xi Jinping at the Belt and Road forum in Beijing on May 18, Fijian Prime Minister Frank Bainimarama shut down his country's representative office in Taipei the next day. Only 21 small nations offer diplomatic recognition to Taiwan.
Australia, which abides by the One China policy, was among the four major countries to risk China's ire and speak in Taiwan's support at the opening of the World Health Assembly on May 22.
Australia's Chief Medical Officer, Brendan Murphy, told the meeting it was "Australia's strong view" that the World Health Organisation was unique and needed to be as inclusive as possible.
"The practice over the last eight years of inviting Taiwan as an observer to the WHA was a valuable signal of the WHO's engagement with Taiwan and Australia supports this practice continuing," Mr Murphy said in Australia's opening statement, according to a transcript.
But China's view that Taiwan couldn't attend because Ms Tsai refused to acknowledge the 1992 Consensus prevailed.
Sheryn Lee, a Macquarie University associate lecturer in security studies, says China's moves to cut off Taiwan's voice in the international area have "taken a step up" since Ms Tsai's inauguration, and have a long-term objective of reunification.
"Taiwan receives less and less recognition for its de facto sovereignty," she says.
"I think the election of Trump and his phone call [with] Tsai definitely did not help. Taiwan-China relations must also consider the US and its security guarantee for Taiwan. If the US's 'strategic ambiguity' approach becomes dismantled because of Trump's erratic [behaviour], then Taiwan-China relations will worsen."
Ms Lee says Ms Tsai was voted in to address domestic socio-economic problems, so both political parties in Taiwan are invested in maintaining the status quo in cross-strait relations.
But she says clearly acknowledging the 1992 Consensus would be a "political nightmare" for Ms Tsai, as 42 per cent of voters in Taiwan are swing voters.
Jerome Cohen, an NYU law professor and senior fellow at the US Council on Foreign Relations think tank, says the same-sex marriage ruling was "a shot in the arm for Taiwan's standing in the world".
His former students famously include the last president, Mr Ma.
Professor Cohen wrote that Taiwan's constitutional court ruling "reminds people of the immense progress [Taiwan] has made, although a Chinese civilisation, in instituting legal protection for human rights, judicial independence, separation of powers and all the other 'Western values' openly condemned on the [Chinese] mainland at present."
News of Taiwan's same-sex marriage ruling ricocheted through Australian social media, where politicians, same-sex marriage advocates and opponents alike were reminded that Taiwan is different to China.
Professor Cohen points out Taiwan's national security and survival depend on the willingness of the US, Japan and other democratic countries to guarantee its protection against the threat of military action by mainland China.
"That willingness will turn in large part on the extent to which those countries are aware of Taiwan's accomplishments in achieving political freedoms," he wrote.
