BEIJING — The United States and China ended trade talks in Beijing on Sunday without any announced deals and with Chinese officials refusing to commit to buying more American goods without a Trump administration agreement not to impose further tariffs on Chinese exports.

“If the United States introduces trade measures, including an increase of tariffs, all the economic and trade outcomes negotiated by the two parties will not take effect,” China said in a statement distributed by the state-controlled news media.

The apparent impasse left the Trump administration with the issue of what to do about China’s industrial policies. It also left unresolved an awkward issue for both sides: the Chinese telecommunications company ZTE, which had violated sanctions against North Korea and Iran.

President Trump had sent to the talks what was essentially an export promotion team led by Commerce Secretary Wilbur Ross and including senior officials from the Treasury and from the Agriculture Department. Conspicuously absent were top officials from the Office of the United States Trade Representative, which has threatened to impose 25 percent tariffs on $50 billion a year in Chinese goods, in addition to the tariffs already imposed on $3 billion a year in Chinese steel and aluminum exports.
