Nearly 4,000 cyberattack incidents originating from Taiwan were investigated by the Chinese mainland last year, a mainland spokesman said on Wednesday.

Peng Qing'en, spokesman for the State Council Taiwan Affairs Office, told a news conference that Taiwan's Democratic Progressive Party authorities have repeatedly directed military intelligence agencies and online "cyber forces" to carry out attacks and sabotage against the mainland, spreading illegal and harmful information.

According to Peng, relevant departments investigated and handled nearly 4,000 such incidents, representing a 25 percent increase year-on-year. These attacks primarily targeted key sectors on the mainland, including transportation, finance, technology, and energy, to steal sensitive information, Peng said.

Peng refuted a report recently released by the DPP authorities, which claimed that the mainland had conducted a "comprehensive cyber intrusion" against key infrastructure on the island.

He criticized the DPP authorities for habitually spreading rumors, making false accusations, and smearing the mainland, even at the expense of escalating cross-Strait tensions.

Peng condemned the DPP authorities for doing this to cover up their governance failures, divert public dissatisfaction, and pursue political self-interest.

Previously, the mainland investigated and disclosed cyberattacks against it carried out by organizations, including Taiwan military's "psychological warfare unit" and "Anonymous 64".
