以其人之道，還治其人之身
paying them back in their own coin
6月8日，趙立堅針對關於反外國製裁法立法目的提問做出回應：
為了堅決維護國家主權、尊嚴和核心利益，反對西方霸權主義和強權政治，今年以來，中國政府已多次宣布對有關國家的實體和個人實施相應反製措施。“以其人之道，還治其人之身”。
In order to resolutely safeguard national sovereignty, dignity and core interests and oppose Western hegemonism and power politics, the Chinese government has launched multiple corresponding countermeasures against entities and individuals of relevant countries since the beginning of 2021. It's paying them back in their own coin.
Paying someone back in their own coin，這句英語習語，指有人很糟糕地對待你，你也以同樣方式回敬對方，與中文的“以其人之道，還治其人之身”“以牙還牙”有異曲同工之妙。
