Former Bank Negara governor Zeti Akhtar Aziz has called for a rational view of China's investments in Malaysia, amid concerns that national interests are being undermined and sold to the eastern superpower.

"Investments from China only account for 2 percent of Malaysia foreign investment. The rest are from US, Europe, Japan and Korea.

"We must analyse this in a rational manner. As an economist, I will analyse it by case study," Zeti said in an interview with Sin Chew Daily.
