More than half the food products that cross borders are imported, according to an annual report by the International Food Industry Association.
The report, published this week, shows that the total volume of goods traded is on track to grow by 25% to 29% annually by 2020.
The IFA, an industry trade group, has been warning for years that food trade in the US is set to become increasingly fragmented and that there is little chance of a trade deal being struck by the end of the year.
Its report also found that the global trade in food has been on track for a 16-year high.
“Food imports are set to be at their highest level since 1999,” it said.
In the US, the trade is set at $4.5 billion per year, which is up 9% year on year to $4 billion.
The report found that, in China, where there are a huge number of exporters, the total number of imports has fallen by 14% over the past decade, while the number of exports is up by 10%.
In Japan, imports are down by almost 8% year-on-year.
In India, imports from the US have fallen by a third since 2007 and the country is set for a 15% decline in the next decade.
The US is not alone in its food exports decline, with other countries such as Mexico and India showing significant declines.
