BEIJING -- China announced Friday a list of U.S. goods including pork and aluminum pipe it says may be hit by higher tariffs. President Trump signed a memorandum Thursday directing the U.S. Trade Representative to impose an estimated $50 billion in tariffs on China, which will go into effect in at least 45 days.

The Commerce Ministry on Friday called on Washington to reach a negotiated settlement of the dispute "as soon as possible" but gave no deadline.

It said China last year bought about $3 billion worth of the goods affected by the proposed higher tariffs.
