The US and China are about to start a fresh round of talks in Beijing as they edge closer to resolving their damaging trade dispute.
The bilateral talks will be led by US Trade Representative Robert Lighthizer and Chinese Vice Premier Liu He.
The discussions have dragged on for months, with both sides struggling to agree on key issues.
For the past years, the trade war has hurt the economy and challenged the multilateral system that has governed world trade for decades.
In recent months, there has been cautious optimism surrounding the talks but also a sense that both sides remain divided on some points.
The US, which accuses China of unfair trading practices, imposed tariffs on $250bn of Chinese products last year.
Beijing has retaliated with duties on $110bn worth of American products.
Tariffs on $200bn worth of Chinese goods were due to more than double at the start of the year, rising from 10% to 25%.
