The tickets were paid for in cash
This certainly raises some questions, but it's also possible that considering the international range here, that this has more to do with Iran's international drug operations, than with a bombing of the plane.
Muslims have begun escalating their conflict with China, and it's entirely possible that a Muslim terrorist group has decided to retaliate by targeting a plane with a large number of Chinese passengers, but if Iran was stupid enough to target China, even covertly, it's going to discover the difference between American leftists and Chinese leftists.
Beijing sent two delegations here Monday to probe stolen passports as reports surfaced that an Iranian man purchased the two tickets used by those passengers on the Malaysia Airlines flight that disappeared Saturday off the coast of Vietnam.
Chinese diplomat Guo Shaochun arrived with a 10-member working group from the Chinese ministries of foreign affairs, transport, public security and the civil aviation administration. Earlier, a team from China's Ministry of Public Security arrived to discuss the passports with their Malaysian counterparts.
The passports, one Italian and one Austrian, were stolen in Thailand in 2012 and 2013. CNN and the Financial Times, citing Thai police, reported that an Iranian man named Kazem Ali purchased the tickets used with the passports for two friends who he said wanted to return home to Europe. The tickets were paid for in cash, the reports said.
In Beijing, foreign ministry spokesman Qin Gang said the Chinese government "urges the Malaysian side to step up their efforts to speed up the investigation and provide accurate information to China in a timely fashion."
The Global Times, a leading Chinese Communist Party newspaper, was less diplomatic. "The Malaysian side cannot shirk its responsibilities," said a biting editorial. "The initial response from Malaysia was not swift enough. There are loopholes in the work of Malaysia Airlines and security authorities."
If this was a Muslim terrorist attack, then the perpetrators should have studied up on China's response to the Mekong River Massacre. China went outside its borders, coordinated the search for the druglord responsible, extradited him and his gang, and executed them.
