Madhu.T.KThere are a few things to be made clear.
1. How many employees are there in your establishment?
2. Did you have an office in India when you joined in 2017?
3. Did you have continuous service in the company with each year of service contributing to at least 240 days in each year?
Only establishments having an office in India with at least 20 employees will be covered by Payment of Gratuity Act. It is immaterial from which office, ie, whether from the HO in China or from the subsidiary company, you receive salary but what is important is that you should have received your salary in India for at least 240 days in each year. This shall also include any service abroad on any work arrangement as an extension of service in India.
