Food technology crucial

Comment on "Summit must focus on food security" (China Daily, May 18)

Technological innovations such as biotechnology, nanotechnology and biofortification are crucial to increasing agricultural productivity, building resilience to weather-related shocks, enhancing the nutritional value of food crops, and ensuring food safety. Biotechnology has great potential to improve crop yield, nutrition and resilience to natural damages, which will be even more frequent in the future due to climate change.

Improve after-sales service

Comment on "Character building holiday destinations" (China Daily, May 3)

Many Chinese firms are good at high-pressure sales but poor at after-sales service. Buying a brand-new commodity is a gamble. The seller always tries to avoid his responsibilities, even within the so-called warranty period.

The primary objective of companies is to sell rather than provide a service, because for them there is no profit to be made in a service. Generally speaking, enterprises need to build up a service culture, but it will take ages to reset their mindset.
