Washington — The United States and China moved to the brink of a trade war Friday when Beijing said it would hit back with 25 percent tariffs on American goods including cars and farm products. The threat of retaliation came after President Donald Trump said earlier in the day that a 25 percent duty on up to $50 billion in Chinese imports would take effect July 6.

In announcing the U.S. tariffs, Trump said he was fulfilling a campaign pledge to crack down on what he contends are China's unfair trade practices and its efforts to undermine U.S. technology and intellectual property.
