The Caia (Portuguese pronunciation: [ˈkajɐ]) or Caya is a river in the Iberian Peninsula, a tributary to the Guadiana. It is one of the main water courses in the Portalegre District, Portugal. Portugal does not recognise part of the border along the Guadiana between the rivers Caia and Ribeira de Cuncos, since the annexation of Olivenza by Spain in 1801. This territory, though de facto and de jure Spanish, remains de jure disputed by Portugal.
The Convention of Limits (1926) was a convention signed between Portugal and Spain, signed on 29 of June 1926, in Lisbon.
Portugal and Spain signed an agreement demarcating the border from the confluence of Ribeira de Cuncos with the Guadiana, just south of Olivenza, to the estuary of the Guadiana River, on the far South. The border between Portugal and Spain from the confluence of the Caia (river) to the confluence of the Ribeira de Cuncos is not demarcated and remains so nowadays, with the Guadiana River being the de facto border.
