China is pouring an estimated $60 billion into Pakistan as part of its Belt and Road Initiative (BRI), but financial experts CNBC spoke to were uncertain how this would impact Islamabad's profile as an investment destination.

The China-Pakistan Economic Corridor (CPEC), as this leg of China's massive regional infrastructure spending push is known, will boost Pakistan in the eyes of investors, said Farrukh Khan, a specialist on the country's economy.

"I would expect other foreign direct investment flows to increase as the CPEC projects near completion and resolve some of the infrastructure shortcomings in Pakistan, particularly energy," he said via email.

But not everyone agrees. "Chinese activity in Pakistan is certainly raising Pakistan's profile, but only in a narrow way," Derek Scissors, an expert in the region at the American Enterprise Institute, told CNBC.

"International investors are attracted to improved infrastructure but they are less drawn by what Pakistan itself has accomplished and more by what China has done in Pakistan."

China and Pakistan's collaboration under the BRI spans a 1,864-mile-long corridor from the city of Kashgar in China's western autonomous Xinjiang region to the Pakistani port of Gwadar. It includes the construction of motorways, railways and power plants, and will also make inroads into sectors such as communication and education.

According to Khan, the scheme had also led to a "significant uptick in investment by domestic business groups."
