In Kabul, Zhou held a meeting with Afghan President Hamid Karzai.

Zhou said the Chinese government fully respects the right of the Afghan people to choose their own path of development and will actively participate in Afghanistan's reconstruction.
The four-hour visit had not been announced by Beijing due to security concerns, state run Xinhua news agency reported.
It followed a two-day trip of Zhou to Singapore, where he met Singaporean leaders on bilateral ties.
