Before marketing it abroad China has gone in for a massive expansion of bullet trains. Currently it has 40 rail lines stretching up to 16,000 kms, the world's largest high speed rail network.

After years of intense lobbying with several countries, including India, in an effort to sell its high-speed rail technology, China has finally bagged its first ever overseas bullet train project signing a $5.5 billion deal with Indonesia.

The two countries inked an agreement in Jakarta on Friday to launch a joint venture for a high-speed rail linking the Indonesian capital with Bandung, the capital of West Java "in a breakthrough deal," state-run Global Times reported.

Speaking at the signing ceremony, Chinese Ambassador Xie Feng said the high-speed rail would be China's first overseas project entirely using Chinese technology and the largest investment value ever.
