SharkLaser writes: In a leaked letter sent to Spain's outgoing President, the US ambassador warned that if Spain didn't pass SOPA-like file-sharing site blocking law, Spain would risk being put into United States trade blocklist. United States government interference in Spain's intellectual property laws have been suspected for a long time, and now the recent leaks of diplomatic cables confirm this. Apart from the cables leaked earlier, now another cable dated December 12th says U.S. expresses "deep concern" over the failure to implement SOPA-style censorship law in the country. "The government has unfortunately failed to finish the job for political reasons, to the detriment of the reputation and economy of Spain," read the letter. Racing against the clock in the final days of the government, Solomont had one last push. "I encourage the Government of Spain to implement the Sinde Law immediately to safeguard the reputation of Spain as an innovative country that does what it says it will, and as a country that breeds confidence," he wrote.
