The Xi'an International Horticultural Exposition's organizing committee has even more reason than just the expo itself, to congratulate themselves.

They signed a cooperation memorandum with the Taipei International Flora Exposition, this past July, which hit a new high point in exchange programs between the mainland and Taiwan.

"This cooperation can be seen as another great event, following the opening of a direct air link between Xi'an and Taipei, in 2008. That raised communication between the two cities to a higher level," said Wang Jun, head of publicity for the Xi'an Party committee who went on to call it a "match made in heaven".
