Oracle announced Tuesday it would expand the reach of products that allow clients to monitor or initiate conversations about their brands on platforms such as Twitter to support Portuguese, Spanish and Chinese language social networks.

This would let Oracle mine more platforms including SinaWeibo, a Chinese microblogging network similar to Twitter, and Vostu, a social gaming site based in Buenos Aires, for potential sales leads.

Oracle’s announcement follows a similar move last week from Salesforce, which launched social monitoring services for Russian and Chinese language platforms including Sina Weibo. Oracle is currently hosting OpenWorld Shanghai, a four-day expo in China showcasing its software services.

The Redwood Shores, Calif.-based company’s recent activity signals the urgency with which IT firms are pursuing Chinese markets, according to Michael Barnes, vice president and research director at research firm Forrester Research’s office in Singapore.

“With a total population of over 1.3 billion people and IT spending growth for 2013 above 10 percent, China market potential is far too great for companies like or Oracle to ignore,” Barnes wrote in an e-mail.

“For both vendors, the goal is the same – help China-based organizations more effectively leverage social media to compete in an already massive, but still rapidly growing, and increasingly competitive market.”
