特朗普总统（President Trump）5月份在将美国撤出伊朗核协议时立即签署了一项命令，恢复实施对伊朗政权和伊朗关键经济行业的最大限度制裁。

特朗普政府给予世界各地企业一定时间，结束与伊朗的各种商务往来。美国于8月7日恢复了对伊朗汽车业、黄金和其他主要金属贸易以及货币交易的制裁。

在11月4日午夜，工商企业必须停止购买伊朗石油，否则将被禁止在美国做生意。

美国政府在第二个最后期限到来前的几周内所发出的信息再明确不过。

正如特朗普总统9月对联合国安理会（United Nations Security Council）所说，“美国将致力于增加制裁，并且是比过去更严厉的制裁，以抗击伊朗所有各种恶意行径。任何个人或实体如不遵守这些制裁的规定将面临严重后果。”

The sanctions countdown clock is ticking

When President Trump withdrew the United States from the Iran nuclear deal in May, he signed an order immediately reimposing the highest level of sanctions on the Iranian regime and critical sectors of Iran’s economy.

The administration gave businesses worldwide time to wind down any business with Iran. U.S. sanctions on Iran’s automotive sector, its trade in gold and other key metals, and its currency trading went back into effect on August 7.

As of midnight November 4, businesses must stop buying Iranian oil or be barred from doing business in the United States.

With this second deadline just weeks away, the U.S. government’s message could not be clearer.

As President Trump told the United Nations Security Council in September, “The United States will pursue additional sanctions, tougher than ever before, to counter the entire range of Iran’s malign conduct. Any individual or entity who fails to comply with these sanctions will face severe consequences.”
