CHIAYI, Taiwan -- Taiwan has deployed the most advanced version of the F-16 fighter jet in its air force, as the self-ruled island steps up its defense capabilities in the face of continuing threats from China, which claims it as part of its territory.
Taiwan's President Tsai Ing-wen commissioned into service Thursday 64 upgraded F-16V fighter jets at an air force base in Chiayi. The aircraft represents part of Taiwan's total 141 F-16 A/B jets, an older model from the 1990s that will be completely retrofitted by the end of 2023.
Tsai said the upgrade project showed the strength of Taiwan's cooperation with the U.S. defense industry. It comes at a time the island's status has become a major point of tension in the U.S.-China relationship.
Beijing has been stepping up its threat by sending fighter jets in combat formations into Taiwan's buffer zone southwest of the island on a regular basis, along with longer-range missions into the Western Pacific.
China has increased its rhetoric as well, with President Xi Jinping telling President Joe Biden during a virtual summit this week that challenges to China's claim over the island amounted to playing with fire.
China and Taiwan split during a civil war in 1949, and Beijing has not ruled out using force to reunify with the island.
The United States' "One China" policy recognizes Beijing as the government of China but allows informal relations and defense ties with Taipei.
"This represents the steadfast promise of the Taiwan-U.S. partnership," Tsai said. "I trust that in holding fast to democratic values, there will definitely be more countries with similar values who will stand with us on this front."
In Beijing, Foreign Ministry spokesperson Zhao Lijian reiterated China's opposition to official contacts between Taiwan and the U.S. and hopes that Washington will "be cautious with its words and actions on the Taiwan issue, and refrain from sending any wrong signals to the secessionist forces of Taiwan independence."
"The crux of the tension in the Taiwan Strait is that the secessionist forces of Taiwan independence are sparing no effort to split the country and collude with external forces," Zhao told reporters at a daily briefing. "What they are doing is just like an ant trying to topple the giant tree, which will surely end up in failure."
In Chiayi, pilots in F-16s showed off complex maneuvers on Thursday, flying low across the skies. Sandra Oudkirk, the director of the American Institute in Taiwan -- the U.S. de facto embassy in Taiwan -- was in attendance as well.
The F-16V is the most technologically advanced version of the storied multi-role fighter jet, equipped with highly capable radar, allowing it to track more than 20 targets at a time. It also features cutting-edge electronic warfare systems, along with advanced weapons, precision GPS navigation and a system to automatically avoid collisions with the ground.
The planes represent the most advanced of the fourth generation of fighter aircraft, but are still below the latest fifth generation such as the U.S. F-22 and F-35, and Russia's Su-57 and China's J-20. Taiwan has mooted the idea of purchasing fifth generation aircrafts from the U.S. but the F-16 upgrade was decided as the most effective measure under present circumstances.
With the upgrades and the planned delivery of 66 new F-16Vs in 2023, Taiwan will be the largest operator of F-16s in Asia, said Kitsch Liao, a military and cyber affairs consultant for DoubleThink Lab, an organization targeting disinformation.
This means the island should invest in repair centers for the jets to improve readiness, Liao said. Previously, Taiwan had to send the jets to other countries for repair.
