BEIJING -- China has introduced unilateral visa-free entry and mutual visa exemption agreements with 75 countries as part of its efforts to streamline visa rules and promote international exchange, an immigration official announced at a press conference on Wednesday.

Wang Zhizhong, head of the National Immigration Administration (NIA), also noted that during the 14th Five-Year Plan period (2021-2025), the number of countries eligible for visa-free transit to China has increased to 55, while the number of entry ports has expanded to 60 across 24 provinces, autonomous regions and municipalities.

Additionally, the allowed stay period for visa-free transit has been extended to 240 hours, according to Wang, adding that all these measures have greatly facilitated travel for foreigners visiting China for tourism, business and other purposes.

These optimized visa-free policies have also strengthened exchanges and interactions between Chinese citizens and people around the world, fostering closer ties and deeper friendship, Wang noted.

"Many foreign visitors have gained a true and full understanding of China through their firsthand experiences," Wang said.

During the 14th Five-Year Plan period, China's border inspection agencies have handled a total of 1.556 billion entries and exits by travelers, along with more than 98 million cross-border transport vehicles, including aircraft, ships, trains and automobiles, according to official data.

"China is now among the countries with the most efficient port clearance systems in the world," Wang said.

Wang also highlighted the NIA's efforts to improve policies and mechanisms for attracting global talent and expertise. The administration has been working to establish a comprehensive support system that covers entry visas, stay and residence permits, as well as other related services.

"Many high-level international professionals have come to China to support its modernization drive, actively contributing to a range of key sectors," Wang said.
