交往(jiāo wǎng) - to associate with, to have dealings with; to go out with in Mandarin

交往 (jiāo wǎng) is contact between people that goes both ways over time: keeping company, having dealings, staying in touch. It covers friends, neighbours, colleagues and whole organisations, and it works as a noun as well, so 我们没有交往 means we have no contact.

In the right context it also means dating. 他们交往了三年 will be read as they were together for three years, and 和她交往 is going out with her. Nothing in the word says romance; the situation does, and Mandarin is content to let it.

The trap is the grammar. 交往 is mutual, so the other party is marked with 和 or 跟 rather than dropped in as an object: 和他交往, never 交往他. English lets you date someone directly, and that habit produces the commonest mistake with this word. Note also that plain 认识 is only knowing who someone is, while 交往 implies an ongoing relationship.
