Taiwanese President William Lai is facing challenges from China, including both overt hostility and covert attempts to influence the island. In late March, several Taiwanese soldiers were imprisoned for selling sensitive information to China. This occurred after Lai delivered a speech condemning the Chinese Communist Party (CCP) in strong terms, vowing to resist manipulation and punish those showing loyalty to China.

Lai is aware of China's "carrot and stick" approach and has warned Taiwanese citizens about the CCP's "United Front" strategy. This strategy involves China using various means, including financial incentives, to infiltrate international organizations and influential groups, planting agents to build alliances.

The Taiwanese government is working against a tide of Chinese covert actions, backed by substantial financial resources. Recently, a consultant to the Presidential Office and two others from the ruling party were reportedly detained on suspicion of spying for the CCP.

Lai's strong stance has been welcomed by many Taiwanese, who felt the island had been too vulnerable. The government is also taking a tougher approach to Chinese infiltration, revoking the Taiwanese nationality of citizens found to possess Chinese identity cards.

While some Taiwanese seek Chinese ID cards for convenience, the government has signaled an end to divided loyalties. The National Immigration Agency has revoked visas of Chinese citizens for violating local laws through online content.

Taiwan has relatively liberal free-speech laws, but advocating for the violent overthrow of the government by China's military is considered a red line. One Chinese national, who lived in Taiwan on a spousal visa, openly supported China's annexation of Taiwan.

Some analysts view Lai's actions as primarily political, aimed at regaining control of Taiwan's parliament and building momentum for upcoming local elections. They also suggest the ruling party is seeking to gain favor with the Trump administration and align with its tough stance on China.

Lai's actions align with the approach of China hard-liners in the Trump administration. A majority of Taiwanese appear to support tougher measures against threats to national sovereignty. Some analysts note the timing of these actions, coinciding with the ruling party's efforts to remove opposition legislators and win local elections, with the goal of securing Lai's re-election.
