The United States and China are due to begin a fresh round of talks in Beijing on Tuesday as they edge closer to resolving their damaging trade dispute.
The discussions will be led by US Trade Representative Robert Lighthizer and Chinese Vice Premier Liu He.
Talks have dragged on for months, with both sides struggling to agree on key issues.
The trade war has hurt the economy and challenged the multilateral system that has governed world trade for decades.
There has been cautious optimism surrounding the talks in recent months but also a sense that both sides remain divided on some points.
