There are a number of options for the US. It could, for example, not be involved in the trade talks (it wasn't originally); it could make demands that crash them; it could make ludicrous demands and have them acceeded to; or it could negotiate as a partner to the other members. I suspect that the only two outcomes that are regarded as succesful is a multilateral treaty on US terms, or no multilateral treaty at all. The last thing the US wants is a multilateral treaty between East Asian and Pacific nations, which the US regards as its back yard.
