Chinese mainland and Taiwan signed agreements Sunday on launching regular flights across the Taiwan Straits, and boosting cooperation in finance and handling criminal proceedings.

They also reached a consensus on allowing mainland companies to invest in Taiwan.

During Sunday's talks, the mainland-based Association for Relations Across the Taiwan Straits (ARATS) and the Taiwan-based Straits Exchange Foundation (SEF) agreed to "actively encourage and promote mainland companies to conduct inspections and invest on the island".

Wang Yi, a senior official in charge of Taiwan affairs in the Chinese mainland, said the three agreements and one consensus reached during this round of talks indicate new achievement in cross-Strait relations. Sunday's talk in Nanjing marks the third round of talks in less than a year between chief negotiators from both sides of the Taiwan Strait.
