Hopes are high AfCFTA will help unlock Africas long-stymied economic potential by boosting intra-regional trade.

African leaders launched a continental free-trade zone that, if successful, would unite 1.3 billion people, create a $3.4 trillion economic bloc, and usher in a new era of development.

After four years of talks, an agreement to form a 55-nation trade bloc was reached in March, paving the way for SundaysAfrican Unionsummit in Niger whereGhanawas announced as the host of the trade zones future headquarters and discussions were held on how exactly the bloc will operate.

It is hoped the African Continental Free Trade Area (AfCFTA) – the largest since the creation of the World Trade Organization in 1994 – will help unlock Africas long-stymied economic potential by boosting intra-regional trade, strengthening supply chains, and spreading expertise.

The eyes of the world are turned towards Africa, Egyptian President and African Union ChairmanAbdel Fattah el-Sisisaid at the summits opening ceremony.

The success of the AfCFTA will be the real test to achieve the economic growth that will turn our peoples dream of welfare and quality of life into a reality, he said.

Africa has much catching up to do: Its intra-regional trade accounted for just 17 percent of exports in 2017 versus 59 percent in Asia and 69 percent inEurope. Africa has missed out on the economic booms that other trade blocs have experienced in recent decades.

Economists say significant challenges remain, including poor road and rail links, large areas of unrest, excessive border bureaucracy, and petty corruption that have held back growth and integration.

Members have committed to eliminating tariffs on most goods, which will increase trade in the region by 15 to 25 percent in the medium term, but this would more than double if these other issues were dealt with, according to International Monetary Fund (IMF) estimates.

The IMF in a May report described the free-trade zone as a potential economic game changer of the kind that has boosted growth in Europe and North America, but it added a note of caution.

Reducing tariffs alone is not sufficient, it said.

Africa already has an alphabet soup of competing and overlapping trade zones – ECOWAS in the west, EAC in the east, SADC in the south and COMESA in the east and south.

But only the EAC, driven mainly byKenya, has made significant progress towards a common market in goods and services.

These regional economic communities (REC) will continue to trade among themselves as they do now. The role of AfCFTA is to liberalise trade among those member states that are not currently in the same REC, said Trudi Hartzenberg, director at Tralac, aSouth Africa-based trade law organisation.

The zones potential clout received a boost on Tuesday when Nigeria, the largest economy in Africa, agreed to sign the agreement at the summit. Benin has also since agreed to join. Fifty-four of the continents 55 states have now signed up, but only about half of these have ratified.

One obstacle in negotiations will be the countries conflicting motives.

For undiversified but relatively developed economies such as Nigeria, which relies heavily on oil exports, the benefits of membership will likely be smaller than others, said John Ashbourne, senior emerging markets economist at Capital Economics.

Nigerian officials have expressed concern the country could be flooded with low-priced goods, confounding efforts to encourage moribund local manufacturing and expand farming.

In contrast, South Africas manufacturers, which are among the most developed in Africa, could quickly expand outside their usual export markets and into West and North Africa, giving them an advantage over manufacturers from other countries, Ashbourne said.

The presidents of both countries attended the summit.

The vast difference in countries economic heft is another complicating factor in negotiations. Nigeria, Egypt and South Africa account for more than 50 percent of Africas cumulative GDP, while its six sovereign island nations represent about 1 percent.

It will be important to address those disparities to ensure that special and differential treatments for the least developed countries are adopted and successfully implemented, said Landry Signe, a fellow at the Brookings Institutions Africa Growth Initiative.

The summit also saw the launch of a digital payments system for the zone and instruments that will govern rules of origin and tariff concessions, as well as monitor and seek to eliminate non-tariff obstacles to trade, the AU said.
