Are there any restrictions on remittance from China to American personal accounts?

According to American tax law, every American can accept remittance in US dollars from foreign countries, non-American citizens and non-immediate family members, with a lifetime limit of no more than US$ 5 million. More than just taxes are needed. If it exceeds100000 USD per year, it is recommended to declare (not tax, but declaration record). The limit in China is $50,000 per person per year.
