He said tourism, the fastest growing sector in the economy, could only thrive in a peaceful and stable environment.
"We are all aware of what happens when a tourism destination is plagued with violence and insecurity," Mzembi told journalists on Wednesday.
He noted that attractive destinations in turmoil-hit North Africa were losing tourists to Southern Africa which he said was rapidly becoming a haven of peace.
"So we need to keep Zimbabwe and the region peaceful and secure," he said while also stressing the importance of peaceful elections envisaged soon.
Zimbabwe's tourism sector has registered phenomenal growth in recent years and has overtaken agriculture to become the second largest contributor to Gross Domestic Product after mining.
Mzembi said the sector’s contribution to GDP was expected to rise from 9 percent last year to 15 percent and to double tourist arrivals to 5 million by 2015.
However, the minister expressed concern that Zimbabwe’s traditional source markets in Europe were discouraging their nationals from traveling to Africa and other developing countries.
Following the economic meltdown, the European Union has urged member countries to introduce various airport departure taxes which make it more attractive for Europeans to visit within their own countries and the EU rather than venture far out, he said.
Mzembi said it was therefore important for Zimbabwe and the Southern African region to develop strategies that will ensure the survival and growth of their tourism sectors.
Integration of the region into a single tourism destination was one such strategy, underpinned by the region's transfrontier conservation areas such as the Kavango-Zambezi and the Great Limpopo.
Kavango-Zambezi is potentially the world's largest conservation area, spanning five southern African countries: Angola, Botswana, Namibia, Zambia and Zimbabwe, and is centered around the Caprivi- Chobe-Victoria Falls area.
The Great Limpopo Transfrontier Conservation Area comprises three game parks from South Africa, Mozambique and Zimbabwe.
Mzembi said the 2013 United Nations World Tourism Organization (UNWTO) General Assembly to be co-hosted by Zimbabwe and Zambia would help put African tourism on the world map.
