The Washington Post reports: "The United States is "holding a knife to our neck" to force trade concessions, a top Chinese official said Tuesday, a day after the two sides imposed another round of punishing tariffs. With both Beijing and Washington holding their ground, the dispute between the world's two largest economies looks set to rumble on with no obvious end in sight. "Our door is open for the resumption of trade consultations and negotiations, but to make the negotiations effective, they should be based on mutual respect and treating each other as equals," Vice Commerce Minister Wang Shouwen told reporters."
