weibo account

Weibo and WeChat are separate accounts, although you may be able to use WeChat for certain login or verification options. You don’t always need a Chinese number—Weibo can support some international numbers, but availability depends on the country and current verification rules.

Weibo accepts some international numbers but it's hit or miss, and posting needs a verified bound phone. Keep that number long term, they re-verify and losing it basically loses the account.

you dont always need a Chinese number, Weibo can support some foreign numbers, but signup options can vary by country.
