A historic agreement between China and Angus means that Glamis Castle has been twinned with the Great Wall of China.
It is hoped the twinning agreement will help attract tourists
The Great Wall, which is more than 2,000 years old and 4,000 miles long, is only twinned with one other tourist attraction - The Pyramids.
But the Chinese believe they have a lot in common with Glamis Castle in terms of restoration and conservation work.
The twinning agreement has resulted from Angus Council spending years forging links with China.
Both the council and the Chinese authorities believe they will benefit from the deal by sharing web links, ideas on heritage and expertise in conservation.
Angus Council's development officer Jane Clements said: "Obviously, we are hoping more Chinese visitors will come.
"Not only visiting our tourist attractions, but companies and getting out to see the hinterland of Angus. This is good for the economy."
David Adams, general manager of Glamis Castle, said: "The Chinese people are very interested in culture, heritage and built heritage and in particular are interested in the Royal Family and here at Glamis we have all of those."
According to Angus Council's latest figures, 10% of all Angus' exports, worth £13.1m, will go to China in 2007.
A total of 26 companies in the county are actively trading in China and imports are expected to rise from £5.9m this year, to an estimated £9.8m over the next 12 months.
Mr Adams said the castle now had to put itself at the forefront of the Chinese tourist market.
