"China remains ready to continue our talks with our colleagues to reach a conclusion. Our door is still open", Cui said in an interview with Fox News Channel.
The two countries have sought to overcome discord since US President Trump imposed 25 per cent tariffs on $50 billion worth of Chinese goods last June in a bid to balance the trade deficit. Since then, the sides have exchanged several rounds of duties.
The latest hit was made by Washington last week when $200 billion in Chinese goods were subjected to a 25 per cent tariff. Beijing pledged on Monday to retaliate by raising tariffs on $60 billion worth of US imports starting in June.
Trump has said that trade talks with China have not collapsed, despite the fresh set of tariffs the United States imposed on Chinese goods after negotiations seemed to stall.
US Secretary of the Treasury Steven Mnuchin said earlier that he was going to visit China in the near future to continue the negotiations.
Chinese Commerce Ministry spokesman Gao Feng said last week, however, that he had no information about the US delegation's reported plans to visit China for a fresh round of trade talks.
