How to say "I'm very glad you're my business partner" in Chinese

 Here are a few ways to say "I'm very glad you're my business partner" in Chinese, with slightly different nuances:

Formal and polite:

• 我非常高兴能和您成为合作伙伴。(Wǒ fēicháng gāoxìng néng hé nín chéngwéi hézuò huǒbàn.) This is the most formal and generally applicable option. It translates to "I am extremely happy to be able to become partners with you."

• 能和您合作，我感到非常荣幸。(Néng hé nín hézuò, wǒ gǎndào fēicháng róngxìng.) This translates to "Being able to cooperate with you, I feel extremely honored." It emphasizes the honor of the partnership.

Slightly less formal, but still respectful:

• 很高兴能和您合作。(Hěn gāoxìng néng hé nín hézuò.) This is a simpler and more common way to express your happiness. It translates to "I am very happy to be able to cooperate with you."

• 我很高兴有您这样的合作伙伴。(Wǒ hěn gāoxìng yǒu nín zhèyàng de hézuò huǒbàn.) This translates to "I am very happy to have a partner like you." It highlights the quality of the partner.

More casual (use with people you know well):

• 能和你合作真是太好了。(Néng hé nǐ hézuò zhēnshi tài hǎo le.) This is more casual and translates to "It's really great to be able to cooperate with you." Use this only with people you have a more established, friendly relationship with. Note the use of nǐ (you) instead of nín (the more formal "you").

Key vocabulary used:

• 我 (wǒ): I
• 非常 (fēicháng): very, extremely
• 高兴 (gāoxìng): happy, glad
• 能 (néng): can, able to
• 和 (hé): and, with
• 您 (nín): you (formal)
• 你 (nǐ): you (informal)
• 成为 (chéngwéi): to become
• 合作伙伴 (hézuò huǒbàn): business partner
• 合作 (hézuò): cooperation, to cooperate
• 感到 (gǎndào): to feel
• 荣幸 (róngxìng): honored, fortunate
• 真是 (zhēnshi): really

Choose the option that best suits the context and your relationship with the person you're speaking to. The more formal options are generally safer and more appropriate in most business situations.
