Zimbabwe's participation in the multi-billion-dollar Great Limpopo Transfrontier Park (GLTP) is in doubt following bickering over the awarding of title deeds. It has emerged that the private sector, which was billed to develop Gonarezhou National Park, has spurned government's offer for a stake in the initiative unless they are given title deeds for their specific areas of interest. The project, which also involves Mozambique and South Africa, has suffered protracted problems on the Zimbabwean side as there is no development as yet of requisite infrastructure such as roads, bridges, hotels and lodges, a senior official in the Tourism and Environment Ministry said.
