The Mosaique Guinee news website said that the delegation will meet with Colonel Mamady Doumbouya, the rebel leader, in the hotel Riviera Royal in the capital city Conakry.
According to media reports, Doumbouya has already arrived at the hotel.
On Sunday, a group of Guinean military led by the colonel stormed the presidential palace and detained 83-years-old President Alpha Conde Conde. Later, Doumbouya declared the dissolution of the government, the abrogation of the constitution and the closure of borders.
On Wednesday, the ECOWAS suspended Guinea's membership in the organisation, demanding Conde's release.
