The security was tighter than when Premier Wen Jiabao visited. The library, crawling with black-suited men a day earlier, was deserted save for selected Korean-speaking students - summoned hours in advance for the VIP's visit. And he stayed only five minutes. Welcome to foreign tours, Kim Jong-il style. Confirmation of the reclusive North Korean leader's whereabouts came yesterday - three days after his train was reported to have crossed into China - when he was spotted at the Sun Yat-sen University's branch campus in Guangzhou's Xiaoguwei 'university town'. His motorcade swept up to the university library's entrance, where Mr Kim, wearing a grey coat, hat and sunglasses, had a short briefing on the development of Xiaoguwei, a pet project of Guangdong's North Korean-trained Communist Party boss Zhang Dejiang . For the leader of a starving, backward nation who is apparently keen to learn about China's economic opening up in the province where it all began, Mr Kim's visit was brief. Within five minutes he was gone. 'He has a big pot belly,' said a source who witnessed the scene. It may not be much, but it was at least as much as the staff of South Korea's Guangzhou consulate knew yesterday. A consular source said: 'There are many signs that he is here but we have no concrete evidence. It is a good sign that he is visiting Guangdong so that he can see the benefits of opening up.' One source said: 'The security was tighter than when Wen Jiabao visited the campus. Then, the library was closed for only half an hour.' Shenzhen appeared next on Kim's itinerary, with security tight around a hotel often used by state leaders and the Shenzhen TV station awaiting 'an important event'.
