Well for one thing how many million dollar properties did the Chinese government have to buy to put in the track? Remember one end is in LA and the other is in San Francisco.
Even empty farmland in California is $5000-$12000 an acre (4046 sq meters). Those for housing can easily be $1M/acre...and that doesn't include the building on it.
They would certainly have to try and buyout land in mostly undesirable places away from heavily populated areas. This likely is going to make the route not very efficient.
