Updated forecasts from the International Monetary Fund (IMF) show global expansion weakening with the world’s gross domestic product (GDP) growing by an estimated 3.7% in 2018, and forecast at 3.5% in 2019 and 3.6% in 2020. The projections are downward revisions from October’s World Economic Outlook (WEO), in part reflecting the trade war between the United States and China. A tightening of the Chinese economy may be reflected in Beijing’s reappraisal of lending to sub-Saharan Africa.
