On Taiwan’s tiny Penghu islands, the missile bases that sit next to white-sand beaches and bustling fish markets are a visceral reminder of the constant threat of attack from China.
Despite the huge military discrepancy between the two sides, many analysts believe that Taiwan’s location, inhospitable terrain and US support would make a full-scale invasion extremely difficult for China — and possibly too costly to countenance.
Recent record incursions of Chinese fighter jets into Taiwan’s air defense identification zone and increasingly aggressive rhetoric from the administration of Chinese President Xi Jinping (習近平) have raised fears that China might contemplate acting on a pledge to “reunify” Taiwan sooner rather than later.

The Chinese Ministry of National Defense last week said it would “not hesitate to start a war” to “stop Taiwan from becoming independent.”
One US admiral said an attack could come by 2027, the centenary of China’s People’s Liberation Army (PLA).
“If we were to go head to head militarily, we don’t stand a single chance,” said retired admiral Lee Hsi-min (李喜明), who was head of Taiwan’s armed forces until 2019.

However, Russia’s failure to quickly overrun Ukraine stands as a cautionary tale for Beijing, while simultaneously providing Taipei with tactical blueprints and inspiration on how to hold off a much larger enemy.
“Our soldiers here are all Taiwanese and will be fighting to defend their homeland,” said Chen Ing-jin, a Penghu historian and architect. “That makes a difference. Just look at Ukraine.”
Taiwan’s biggest advantage is its geography.
Amphibious assaults are exceedingly difficult, and if China were to invade Taiwan — and, crucially, hold it — Beijing would need to move hundreds of thousands of troops, along with equipment, across the Taiwan Strait.
Even at its narrowest point, the strait is 130km and weather conditions are notoriously unforgiving, especially during two monsoon seasons. That leaves just two brief “windows of attack” — May to July and October — for such a large-scale operation, a US Naval War College report said.
In addition, studded into the waters are outlying islands like the Penghu chain — bristling with radar and missiles pointing out into the strait. With the likely early warning and the weaponry Taipei has at its disposal, the PLA would probably incur high losses in that first stage of transit, said James Char, associate research fellow at Singapore’s S. Rajaratnam School of International Studies.
While the small, flat outlying islands might in the end prove easy for Beijing to subdue, on Taiwan’s main island, the opposite applies.
The coastal terrain “is a defender’s dream come true,” said Ian Easton, author of The Chinese Invasion Threat.
He and his colleagues estimate that Taiwan only has 14 small beaches suitable for landing, and they are bordered by mountains, cliffs or dense urban infrastructure.
“Landing on Taiwan is only part of the problem,” said Bonny Lin (林洋), director of the China Power Project at the Center for Strategic and International Studies.
Progress through Taiwan’s wetlands, mountains and densely populated urban areas would require a huge range of combat skills and weapons.
“How is it going to sustain those forces once they’re in position and advancing?” Lin asked. “How is it going to do the logistics?”
China has spent the equivalent of hundreds of billions of US dollars upgrading its military capabilities over the past decade, and its statistical dominance over Taiwan is enormous.
The PLA has more than 1 million ground force personnel to Taiwan’s 88,000; 6,300 tanks compared with 800; and 1,600 fighter jets to 400, US Department of Defense data show.
Washington also estimates that Beijing has the world’s largest navy by ship number. A recent US Naval War College paper described those ships as “increasingly sophisticated, capable vessels.”
However, many experts, including Char and Lin, question whether they are yet capable enough.
Atlantic Council senior adviser Harlan Ullman put it more forcefully in a February paper: “China simply lacks the military capability and capacity to launch a full-scale amphibious invasion of Taiwan for the foreseeable future.”
In the meantime, Taiwan has plans to counter China’s might in numbers, with Lee highlighting asymmetric warfare — an emphasis on mobility and precision attacks — an approach US officials are reportedly encouraging. Lee pointed to the success of the Ukrainian mobile missile launcher that sank Russia’s Black Sea flagship, the Moskva.
Taiwan has built up stockpiles of mobile missile batteries and shoulder-launched weapons, but he said they need substantially more.
The factor that preoccupies Beijing most is who else might get involved in the conflict, Chinese military expert Song Zhongping (宋忠平) said.
“The difficulty of liberating Taiwan lies in the potential intervention of the United States. It’s the biggest obstacle for the PLA to clear,” he said.
The US officially maintains a policy of “strategic ambiguity” on whether it would intervene militarily in the event of an invasion. Regardless, it supplies Taiwan with military hardware, while US President Joe Biden has said multiple times that Washington would intervene.
The “extent, depth and breadth” of US and other allies’ involvement would greatly determine how any conflict would play out, Song said.
Even without a military intervention, Char said the threat of economic sanctions, such as those placed on Russia, would give Chinese leadership pause for thought.
Whether China would be prepared to cause mass casualties with an invasion, while risking its domestic and international image, is a fundamental question.
“You need to let China know that it will suffer tremendous losses, and even then it may still not be able to occupy Taiwan,” Lee said. “So that China will think that the best way to resolve the Taiwan problem is by peaceful means.”
An increase in Taiwanese boats using China-made automatic identification systems (AIS) could confuse coast guards patrolling waters off Taiwan’s southwest coast and become a loophole in the national security system, sources familiar with the matter said yesterday. Taiwan ADIZ, a Facebook page created by enthusiasts who monitor Chinese military activities in airspace and waters off Taiwan’s southwest coast, on Saturday identified what seemed to be a Chinese cargo container ship near Penghu County. The Coast Guard Administration went to the location after receiving the tip and found that it was a Taiwanese yacht, which had a Chinese AIS installed. Similar instances had also
GOOD DIPLOMACY: The KMT has maintained close contact with representative offices in Taiwan and had extended an invitation to Russia as well, the KMT said The Chinese Nationalist Party (KMT) would “appropriately handle” the fallout from an invitation it had extended to Russia’s representative to Taipei to attend its international banquet last month, KMT Chairman Eric Chu (朱立倫) said yesterday. US and EU representatives in Taiwan boycotted the event, and only later agreed to attend after the KMT rescinded its invitation to the Russian representative. The KMT has maintained long-term close contact with all representative offices and embassies in Taiwan, and had extended the invitation as a practice of good diplomacy, Chu said. “Some EU countries have expressed their opinions of Russia, and the KMT respects that,” he
VIGILANCE: The military is paying close attention to actions that might damage peace and stability in the region, the deputy minister of national defense said The People’s Republic of China (PRC) might consider initiating a hack on Taiwanese networks on May 20, the day of the inauguration ceremony of president-elect William Lai (賴清德), sources familiar with cross-strait issues said. While US Secretary of State Anthony Blinken’s statement of the US expectation “that all sides will conduct themselves with restraint and prudence in the period ahead” would prevent military actions by China, Beijing could still try to sabotage Taiwan’s inauguration ceremony, the source said. China might gain access to the video screens outside of the Presidential Office Building and display embarrassing messages from Beijing, such as congratulating Lai
Four China Coast Guard ships briefly sailed through prohibited waters near Kinmen County, Taipei said, urging Beijing to stop actions that endanger navigation safety. The Chinese ships entered waters south of Kinmen, 5km from the Chinese city of Xiamen, at about 3:30pm on Monday, the Coast Guard Administration said in a statement later the same day. The ships “sailed out of our prohibited and restricted waters” about an hour later, the agency said, urging Beijing to immediately stop “behavior that endangers navigation safety.” Ministry of National Defense spokesman Sun Li-fang (孫立方) yesterday told reporters that Taiwan would boost support to the Coast Guard
