acquaintance

I have many business acquaintances at the annual trade conference.

私は年間取引会に多くの仕事の知り合いがいます。

Although they were only casual acquaintances, they attended the same business conference for three days.

彼らはただの知り合い同士だったが、3日間同じビジネス会議に参加した。

During international business trips, it's often beneficial to cultivate professional acquaintances with local industry leaders.

海外出張中は、現地の業界リーダーと業務上の知人関係を築くことが、しばしば有益です。
