First off it seems China Eastern has a problem with their kg to lbs conversion. They allow 5kgs hand luggage in Economy (this is ca. 11 lbs).
The size is 56x36x23cm
The number of bags allowed is 1. Always go on the assumption that the airline will follow it's own rules and will allow 1 pcs.
They usually do not care and do not enforce their rules but I have never flown them from LA.
