Hailed as an example of good diplomacy and successful negotiated solutions to border problems, the treaty for the territorial swap and border realignment was signed in 2016.[4] The territorial swap saw Belgium giving a total of 40.45 acres of land to the Netherlands comprising two uninhabited riverine peninsulas, previously cut off from "mainland" Belgium by Dutch territory, known as Presqu’île de L’llal and Presqu’île d’Eijsden. In return, the Netherlands gave Presqu’île Petit-Gravier which was 7.63 acres in size, to Belgium.[2]
