"I want to go to China."

Translation: 我想去中国。

[ErmilyPermily]

要 is a much stronger word like "must" and 想 means more "would like to" in regards to a future plan that has not been finalized yet

[josueetcom]

+1. 要 often has the connotation that its already planned/certain so sometimes it gets translated as "will" when followed by a verb.

我要去中国 - also acceptable or is 要 too much like "need" in this context?

Depending on your tone, 我要去中國 can mean want as well, not just need
