The UK and Australia expected to issue 10-year visas
South Korean's move follows other hot Chinese tourist destinations.
The US has issued 10-year multiple entry visas to Chinese since Nov, 2014. They bring additional benefits as they can enter 15 other countries or regions, including Mexico, the Philippines and Chile visa-free.
Canada also launched 10-year visas to Chinese, but only if an applicant's passport validity is longer than 10 years.
In Asia, Singapore issues 10-year visas to Chinese business personnel who regularly enter the country.
The list of countries issuing 10-year visas is growing. The UK has begun to issue two-year multiple entry visas to Chinese tourists and plans to issue 10-year visas in future.
Australia also pushes the 10-year multiple entry visa and is expected to issue it later this year.
