No US president can unilaterally agree to alter the pattern of government support and spending; that is a decision for Congress. Similarly, no Chinese president can unilaterally agree to allow the renminbi to appreciate faster; that is a consensus decision reached together with the various apparatchiks in the State Council and Communist Party.
美国总统不能独自转变政府的支持和支出模式，因为决定权在国会手里。同样，中国国家主席也无法令到人民币加快升值，因为首先必须在人民代表大会和中共内部达成共识。更重要的是，中美两国所必须采取的改革不仅限于这两个层面，而是需要深层次的，根本性的变革。
