Someone else to collect my visa?

Yes, it is ok if you pass him/her the receipt for collection.

Hi! Thanks for the answer.

Is the embassy open as normal Wednesday 27/3?

Yes, sure. You can also check their official website for office hours.

Hi,

What documents do I need to hand in. Is it enough with a scanned copy invitation, copy of pasport of the invitor and copy of his visa? Do I need anything else?

return tickets and hotel reservation are required for business purpose. If you apply in Egypt, 3 months valid residence or above is required as well if you hold Sweden passport.

BTW, the embassy in Egypt has designated some travel agencies for applications, the detailed contacts can be found here http://eg.china-embassy.org/eng/ywzn/lsyw/bszn/t906612.htm
