As a long-time China watcher (hence the Internet alias aka the name of a 2nd century Chinese warlord), I'd be surprised if the Chinese can do anything cheaper in relation to raising livestock. Beef, chicken and pork are all cheaper stateside, based on my occasional readings of news wire items (Reuters, AP, Bloomberg) regarding China. However, if labor is a big part of the cost of alpaca wool, you may have some issues going forward.
Still, the Chinese labor cost advantage isn't what it used to be. Wages there are 4x or more times many countries in the region, including India, Pakistan and much of Central Asia (aka the -stans), which have the climates necessary for wool bearing animals to thrive. They are also not only higher than those in Ecuador, Peru, Bolivia and Paraguay, but also rapidly accelerating. Chinese wages have been held down for a long time via explicit government policy, meaning they have not kept pace with productivity growth, but rising expectations among the Chinese labor force have led to government relaxation of policies that slowed wage growth. Bottom line is that the low wage threat from China is about to disappear, after factoring all the other costs of goods like transportation lead time, energy costs, communication snafus, et al.
That's been the case for many years ~ we can deliver a disease free frozen chicken to an African village for less than it costs to raise and process one there which can be fed without any cost at all.
We almost wiped out the Russian poultry industry with really low cost competition.
