U.S. President Obama and U.S. Trade Representative Michael Froman

The top US trade official has warned China that a proposed bilateral investment treaty and other global negotiations could be in jeopardy if the two sides fail to resolve a stand-off over liberalizing the $2 trillion annual trade in high-tech products.

In an interview with the Financial Times, Mike Froman, the US trade representative, said Washington was eager to use this week's annual US-China Strategic and Economic Dialogue to break the deadlock over updating the 1996 Information Technology Agreement.
