China reunification with Taiwan ‘must’ be fulfilled: Xi Jinping

China's President Xi Jinping has said that "reunification" with Taiwan "must be fulfilled", as heightened tensions over the island continue.

Mr Xi said unification should be achieved peacefully, but warned that the Chinese people had a "glorious tradition" of opposing separatism.

In response, Tsai Ing-wen president of the Republic of China (Taiwan) said "we will not bow to Beijing pressure and our future lay in the hands of our people". Taiwan considers itself a sovereign state, while China views it as a breakaway province.

Beijing has not ruled out the possible use of force to achieve unification.

Mr Xi's intervention comes after China sent a record number of military jets into Taiwan's air defence zone in recent days. Some analysts say the flights could be seen as a warning to Taiwan's president ahead of the island's national day which is on 10th of October.

Taiwan's defence minister has said that "tensions with China are at their worst in 40 years".

But Mr Xi's remarks on Saturday were more conciliatory than his last major intervention on Taiwan in July, where he pledged to "smash" any attempts at formal Taiwanese independence.

Speaking at an event marking the 110th anniversary of the revolution that overthrew China's last imperial dynasty in 1911, he said unification in a "peaceful manner" was "most in line with the overall interest of the Chinese nation, including Taiwan compatriots".

But he added: "No one should underestimate the Chinese people's staunch determination, firm will, and strong ability to defend national sovereignty and territorial integrity."

"The historical task of the complete reunification of the motherland must be fulfilled, and will definitely be fulfilled," he said.

Mr Xi has said he wants to see unification occur under a "one country, two systems" principle, similar to that employed in Hong Kong, which is part of China but has a degree of autonomy.

But Taiwan's presidential office said that public opinion was very clear in rejecting one country, two systems. In a separate statement, Taiwan's Mainland Affairs Council called on China to abandon its "provocative steps of intrusion, harassment and destruction".

Shortly before Mr Xi spoke in Beijing, Taiwan's Premier Su Tseng-chang accused China of "flexing its muscles" and stoking tensions.

Taiwan believes USA can help Taiwan in defending its territory, but the bigger question is Can USA defend Taiwan?

Until recently, the USA believed it could hold Chinese territorial ambitions in check, but the military superiority it long held may not be Enough.

When the Pentagon organised a war game in October 2020, a US "blue team" struggled against new chinese weaponry in a simulated battle over Taiwan.
