Sole proprietor Hong Kong LLC for American citizen...can you set a SEP plan and maximum contributions

[cathomas5591]

Hi all, I run a HK-based LLC sole proprietorship, and have China-based tax residence.   I will have between 1-2 million in earned income in '21, use foreign tax credit reporting, and therefore have no ability to do ROTH or standard IRA.  I want to setup a Simplified Employee Pension plan for the company and deduct pre-tax dollars. 

Three questions:

1. Can I setup a SEP under the conditions above?

2.  What is the maximum amount I can contribute in '21

3.  If cannot do SEP, are there other alternatives to reach the same goal?

Thanks!
