China and the UK have signed a deal to boost the number of flights permitted between the two countries by 50% to 150 per week.
The latest deal follows one agreed in October 2016 agreement, which saw limits on passenger flights between the two countries raised from 40 to 100 a week.
UK's transport ministry says the agreement allows for an expansion in routes from regional airports – potentially boosting local economies and opening up new business and tourism opportunities.
In the first half of the year, 115,000 visits were made from China to the UK, a 47% increase from the same period a year ago.
"These agreements are an important part of preparing Britain for a post-Brexit world and making sure we have access to key markets in the Far East, and they come at a time when our exports are growing and we continue to attract international investment," says UK transport secretary Chris Grayling.
"It just underlines that Britain will do well regardless of the outcome of the Brexit negotiations."
In 2016, restrictions were also relaxed to allow for an unlimited number of cargo flights to operate between the UK and China.
FlightGlobal schedules data shows that Air China accounts for the highest seat capacity between the UK and China (30.2%), followed by British Airways (20.6%) and China Southern Airlines (12.5%).
