China is set to implement provisional tariffs that are lower than the most-favored-nation rates on almost 1,000 imported commodities.

中国将对近 1000 种进口商品实施低于最惠国税率的临时关税。

That is an unconvincing explanation for the weakness of China's nominal growth because GDP should count only the value added to a good in China itself, thus excluding the value of imported commodities.

这是对中国名义增长疲软的一个令人信服的解释， 因为GDP应该只计算中国本身对商品的附加值，从而不包括进口商品的价值。
