14 meat plants have been approved to sell beef into China.
The Department of Agriculture says it brings the total to 21 -- calling it a "strong endorsement of Irish standards".

Talks aimed at resolving the beef price row were adjourned last week, after protesters blockaded the Department of Agriculture.
