Can anyone enlighten me as to who discovered/explored the Hang Tean cave system in Vietnam 2005 please. It's believed to have been a team from the UK

Hey people we have a guest from Stockholm called Lorenz k Rossato who is traveling to Scotland from the 27 Dec until 4 Jan and is hoping to find a friendly caver willing to take him out caving up there, is anyone available or knows someone who would be happy to show our friend around, please...
