Hi Sir/Madam,  This is another paragraph in my wife's CV, appreciate if you can give us a helping hand and check the correctiness..., million thanks

During the past 5 years experience in RST Ltd as Accounts Coordinator, I have gained experience in conducting with clients and suppliers from Mainland China, providing office supports and assisting for public events.  Moreover, I am responsible for company insurance, payroll and administration work to the company.  Being able to speak native Mandarin and type Chinese, it would definitely be my advantage to work people from Mainland China.
