Register a Sole proprietor Company

[midnitesun]

I want to register a sole proprietor company in Singapore. I am a PR and I was checking our ACRA website but I came across this section:

What does a sole-proprietor / partner need to do BEFORE registration?
From 1 January 1994, all self-employed persons are required to top up their Medisave account with CPF Board before they register a sole-proprietorship or partnership, become the new partner of an existing sole-proprietorship or partnership, or renew their business registration. This requirement is only applicable to Singaporean Citizens and Singapore Permanent Residents.

I do not hold any job in Singapore per say because all my business is currently based in Malaysia and I do not contribute to CPF thus I do not have any Medisave.
So does it mean I cannot register a company in Singapore or how do I go about it now.
Thanks
