Taipei on Saturday called on Beijing to abandon what it called its "old mentality", after the Chinese Communist Party's decision to include in its law the rejection of Taiwan independence.

"We call on the new leadership of the Communist Chinese government to abandon its old mentality (based on) conquest and confrontation, and to resolve differences by peaceful, just and realistic means," the Taiwan Continental Affairs Council, the body that sets the Taiwan government's policy on Beijing, said in a statement.

The Communist Party of China on Saturday agreed to make amendments to its charter aimed at consolidating the core position of President Xi Jinping and the guiding role of his political thought within the party, at the conclusion of its congress, which is held twice every 10 years.

The Communist Party also decided to include for the first time a reference in its charter affirming Beijing's "opposition" to Taiwan independence.

The resolution stated that the Communist Party Congress "agrees to include in its charter statements on (...) resolute opposition to and deterring separatists seeking Taiwan independence."

Beijing considers that the autonomous Taipei, an inalienable part of its territory, noting that the Chinese Communist Party never controlled Taiwan, which Taipei rejects.
