Delegates will soon descend on Saudi Arabia for perhaps the most consequential meeting in UNESCO\\u2019s history. With an extended agenda after last year\\u2019s cancellation, it\\u2019s the first World Heritage Committee meeting to be held in-person for four years.

In this episode we examine the so-called \\u2018UNESCO effect\\u2019 - and hear from entrepreneurs around Angkor Wat, in Cambodia, about the mixed consequences of its listing. We also hear from officials in Liverpool, in England, about UNESCO's decision to remove World Heritage status from the city's historic centre and docklands.
