Malaysia's Prime Minister Najib Razak is on a week-long official visit to China. He's expected to sign a number of deals that will strengthen his country's partnership with China.

CCTV correspondent Rian Maelzer visited a ten-year-old special economic region at the southern tip of Malaysia, where Chinese foreign investment has already been having a positive effect.

This year, thanks to Chinese companies purchasing a major independent energy producer, and some huge property deals, China is now Malaysia's number one foreign investor. And it's a similar story here in the Iskandar economic region at the southern tip of the country across the narrow strait from Singapore.

Three major Chinese property developers are building huge residential and commercial projects here with Guangdong's Country Garden leading the way.

Country Garden's most ambitious undertaking is this massive joint-venture with the Johor state royal family. It's rapidly taking shape on four man-made islands off Malaysia's southern coast.

The development spanning nearly 14 square kilometers will see an estimated 100 billion dollars invested over the next 20 years.

China is heavily involved in Malaysian port and rail projects.

And now China Railway Construction Corporation is taking the lead in completing the final segment of double-tracking and electrification of Malaysia's main north-south rail line ultimately linking Iskandar here on the border with Singapore to the border of Thailand in the north.
