将下面的段落翻译成英语。



原文：“贸易顺差”的定义并不真实，因为它没有考虑跨国公司在不同国家的收入和支出。例如，一家中国公司在美国投资或购买产品的支出不计算在中国的贸易顺差中。”
The definition of "trade surplus" is not accurate as it does not take into account the income and expenses of multinational companies in different countries. For example, the spending of a Chinese company on investments or purchases in the US is not included in China's trade surplus.
