Jim Cramer shares insight on the latest economic data out of China and stresses the importance of focusing on the nation's baltic freight data. There was a significant jump in baltic freight and copper is strengthening too. Even though the GDP was better than expected, Cramer is cautious about the data released from the People's Republic of China. Plus, if Germany strengthens and China starts importing and exporting more, domestic consumption should improve. Cramer says he is upbeat on the story in China, even though most are bearish on the nation's economic prospects. He urges investors to stop betting against China in his latest commentary for TheStreet from the floor of the New York Stock Exchange.
