US companies now require a license to continue doing business with any of those firms.
Robert O'Brien, the national security adviser Trump sent in his stead, included the invitation in a letter from Trump that he read at a U.S. -ASEAN meeting on Monday on the sidelines of the summit of the 10-nation Association of Southeast Asian Nations on the outskirts of Thailand's capital.
The first phase of the deal would require China to buy more agricultural products, stabilize its currency and open financial services markets to US firms. In return, Beijing wants the U.S. to do away with new import taxes due to take effect on 15 December on goods including smartphones.
