China's membership of the World Trade Organisation (WTO) has more disadvantages than advantages for Hong Kong 
- because: WTO membership is bad for the labour movement internationally (Charnovitz (1999) )
- but: the liberalization of market access resulting from China's WTO entry will benefit many services sectors which are currently heavily regulated in the country
- because: Hong Kong businesses in China will face increasing competition from multinationals as well as from the Mainland's own developing indigenous business sector
- because: market liberalization resulting from China's admission to the WTO will bring in more outside players to the already developing market
- because: WTO membership is bad for the environment (Charnovitz (1999) )
- because: China's environment affects Hong Kong (China Development Brief (2000) )
- but: experts have estimated that most of Hong Kong's acid rain comes from Hong Kong (Wikipedia (2019))
- because: Hong Kong businesses in China will enjoy less flexibility and special privileges
- because: WTO entry signals the Mainland's move to a more rule-based system, viz. an end to the old way of relying on flexibility and on things to "work themselves out"
- but: there will be market expansion opportunities for many business sectors, especially for trade in goods and services after China's accession to the WTO (english.people.com.cn)
- because: total volume of Hong Kong's entrepot trade and offshore trade and demand for import and export trade related services will increase along with the trade growth
