Anyway some Tips on setting up the news_keywords meta tag:

• Commas are used to separate keywords and are the only punctuation allowed in the field.
• Keywords can be used to disambiguate between like terms. This is perhaps the most useful feature of the new tag; publishers can tell sGoogle when an article is not relevant to a similar topic. The eg. they use to explain this is the World Cup in soccer vs. rugby. Adding < meta name="news_keywords" content="World Cup, Africa 2014, Spain vs Amsterdam, soccer, football"> tells Google the article is not about rugby.
• Each article can have up to ten news keyword phrases. 
• All keywords have equal value; input order doesn’t matter.
