实现互利共赢

You usually use this as a goal or a result. You can say 'we want to 实现互利共赢.' It functions like a formal verb phrase. You will see it in news headlines often. But you can also use it in serious business chats. It shows you are looking for a long-term relationship. It sounds professional and very balanced.

Use it when you are negotiating a contract. Use it when starting a new partnership. It works great in a cover letter too. Even in a serious talk with a roommate about chores! If you propose a plan that helps both of you, this phrase fits perfectly. It makes your proposal sound more legitimate and fair.

Do not use this for tiny favors. If you ask a friend to pass the salt, do not say it. That would be weirdly formal. It is like wearing a tuxedo to a backyard BBQ. Also, avoid it if the situation is clearly one-sided. If you are just taking and not giving, using this phrase will sound sarcastic or even dishonest.

This phrase is a superstar in modern Chinese diplomacy. You will hear it in almost every major speech about international trade. It reflects the traditional value of 'Harmony' (和谐). In China, a deal that hurts one side is seen as a bad deal. Long-term stability is always better than a quick, selfish win. It is about building a 'bigger cake' together.

You might hear people just say 双赢 (shuāngyíng). That literally means 'double win.' It is the shorter, punchier version of the same idea. 互利互惠 (hùlì hùhuì) is another close cousin. It focuses more on the 'mutual benefits' part. But 实现互利共赢 is the most complete and formal way to say it.
