Sri Lanka's first Chinese-built port, a strong symbol of Beijing's investment in South Asia, opened for international shipping on Wednesday with the handling of 1,000 cars from India.
The $1.5-billion deep-sea port in southern Hambantota, the home constituency of President Mahinda Rajapakse, straddles a major east-west shipping lane used by 200 to 300 international vessels daily.
The idea of the project, which was delayed by just over a year, is to create a new logistics hub to handle trans-shipments from the Asian region and provide a boost to Sri Lanka's economy as it recovers from decades of civil war.
Regional power India turned down the offer to construct the deep-sea port saying it was not commercially viable, but China's presence created unease in New Delhi which views Sri Lanka as being firmly in its sphere of influence.
China has since agreed to build a second port in Sri Lanka's capital Colombo and Chinese firms have pledged investments amounting to $50 billion spread over the next 10 to 15 years, according to Sri Lanka's trade ministry.
Elsewhere in South Asia, China has funded port facilities in Pakistan, a long-standing ally, and has plans for rail projects in Nepal, a traditionally India-aligned country where Beijing is increasingly influential.
Bangladesh has asked for Chinese help to build a port and Beijing recently opened an embassy for the first time in the Maldives.
According to Charu Lata Hogg, an analyst at Chatham House, a London-based think-tank, India has come to terms with China in its backyard.
"There seems to be a tacit understanding that their commercial interests can be complementary," Hogg told AFP. "Indian cars going through a Chinese-built port in Sri Lanka reveals a lot about this relationship."
The first shipment of cars on Wednesday in Hambantota, 240 kilometres (150 miles) south of Colombo, came from the south Indian port of Chennai and is destined for Algeria.
The car carrier Asian Sun docked on Wednesday morning to be received by Sri Lanka Port Authority Chairman Priyath Wickrama.
