Investors from all over the world are focusing on Alibaba's IPO and that also includes several Belgian investors. It is highly unlikely small investors will be able to get any shares though.
Alibaba's price evaluation may seem high and was increased only recently, but it is still a highly coveted share, as the company is still cheaper than similar companies. Not only that, Alibaba has been around for quite a while and is therefore a sound investment.
According to Degiro.be, the share attracts a huge amount of interest, with more than 10 times more orders than usual. In the end, Alibaba decides who gets shares, so it may be that no one in Belgium actually gets a part of the Chinese company.
