China forewarned the Trump administration on Sunday that any trade deals currently being discussed will not go into effect should the U.S. implement proposed tariffs on Chinese goods, according to a statement published by the official Xinhua News Agency.

The backdrop: The warning came after a U.S. delegation, led by Commerce Secretary Wilbur Ross, held talks with Chinese officials in Beijing on Saturday and Sunday. The latest, sprawling discussion over trade disputes between both countries ended with neither a joint statement and nor did they released any details, per the AP. The White House had casted doubt on trade talks when it renewed a threat on Tuesday to impose 25% tariffs on $50 billion of Chinese technology this month.
