The U.N. Economic and Social Commission for Asia and the Pacific (UNESCAP) report mainly says good things about Asian economies.

Asia's export-led growth has helped millions of people escape poverty over the past 70 years. Many of the exported products are sold in the United States and Europe.

The writers of the report warned of reduced economic growth in major developing countries if trade protectionism and global insecurity increase. They predicted a lowering of the growth rates by up to 1.2 percentage points.
The report noted that the Asia Pacific region remains "the engine of global growth." But it said pay inequality is increasing and good jobs are difficult to find.
