IDP cannot be issued to holders of foreign driving licences. They must apply for their IDPs in the country that issued their driving licence.
Also, from my knowledge, most countries will not allow drivers with only driving license from China to drive in their countries.
Who Should Apply
For peace of mind when driving overseas, we recommend that Singapore driving licence holders intending to drive in a foreign country to apply for an IDP. The IDP is valid for one year from the date of issue.
Requirements
Agree, i stand corrected.
The applicant must hold a valid Singapore driving licence
Permits cannot be issued to holders of foreign driving licences. They must apply for their IDPs in the country that issued their driving licence
Singaporean applicants must present BOTH a valid driving license and NRIC
Foreigner must also hold employment pass/FIN Card that is valid for 1 year from date of IDP application
Singapore citizens or Permanent Residents who have given up their citizenship or PR status respectively are not allowed to apply for the IDP
Interestingly IDP isn't recognized by China as well:

However, if one has a valid driving license from any of the 32 countries, then you are in luck.
