Wolf- let's put the shoe on the other foot. Let's say there's a huge piece of Chinese land with very few people living there, something like... TIBET. Let's then say there's a country with huge population living next door that previously didn't move into Tibet for a host of reasons. Furthermore, let's say with improvements in Sino-Big Country relations, cross border travels are now common. Finally, Big Country leases land in Tibet for mining, water, and farm/ranch projects. How would the average Han Chinese feel about it? Beijing elites may say all is well, and business is good for both countries, but the common people would be suspicious and maybe even xenophobic.
The average Chinese person on the streets wouldn't be all that bothered by such a development.
What they might question is why the Chinese themselves are not doing all of that, but as Solarz already touched upon, the Chinese are very secure and confident about their national identity, which actively embraces ethnic minorities and have a host of very generous affirmative action style benefits for ethnic minorities not available to Han Chinese.
Something the western media is almost religious in its avoidance of mentioning.
All the so-call discrimination and cultural bias examples the western media delight in hyping up involve people unwilling to learn and use manderan Chinese and/or modern skills and technology. When China builds schools and tries to teach manderan and other key skills to ethnic minority groups to allow them to better take advantage of the opportunities on offer to all Chinese citizens, the same western media screams 'cultural genocide'
To claim discrimination and a lack of good job prospects because you refuse to learn the official government and business language is like a someone claiming discrimation in the UK or US when they can't find a good job because they can't speak or read English.
Anyways, the point is, the average Chinese citizen is far from xenophobic, and are usually very warm and welcoming of foreigners.
So long as this big-country-who-shall-not-be-named and its citizens behave reasonably and within the framework of the original agreement, then there will not be any problems.
There will only be issues if this other country tries a Crimera style take-over or if its citizens start acting badly and establish a bad reputation for themselves inside China.
Because of historical reasons, the average Chinese have a very low tolerance of foreigners trying to throw their weight around inside China and acting like they are better than the Chinese or own the place.
Anyone who behaves like that can expect a frosty reception in China, although that is hardly a uniquely Chinese reaction.
