The course of the border has also been changed several times in recent history. Various agreements, exchange of notes, protocols and contracts were concluded in this regard. Contracting parties were not only the Republic of Italy and the Swiss Confederation, but also entities that have merged into one of these state structures. Important border agreements are:
- The boundaries at Monicello di Finardo and Punta di Polà are, among other things, regulated in the Treaty of Varese ("Regulations and description of the boundaries between the Swiss provincial bailiffs of Locarno and the State of Milan") of June 22, 1754.
- The boundary for the Costa di Sella area between the Swiss municipality of Muggio and the Italian municipality of San Fedele was first established in the agreement ("Regulations and description of the borders of the State of Milan and the Swiss Bailiwick of Mendrisio ") of October 22, 1755.
