For your info, Prof Teerha always be invited from Malaysia and Vietnam every year. He usually ask for our local team support on this matter. I can approve under our medical budget ( for local transportation ) due to small budget. ( 2-4 events per year ). You can put in Medical affair activity - HCP collaboration cost - others. For PR : I can print iHCP engagement approval + transportation invoice to run the process easily and simple.
