visa for entering China!!

Dear Sir,
I have to attend Regional training course, conduct by the International Maritime Organization (IMO) and host by China Maritime Safety Administration (China MSA) which will be held in Beijing, China, from 12 to 16 December 2016.
I am a government officer in Ministry of Transport and Communications and my passport is official one.
So let me know do I need to apply entry permit and if yes, can I apply in China embassy in Yangon, Myanmar?

Best regards,
May Soe Aung
