WASHINGTON: The Islamic State terror group along with climate change are seen as posing a major risk to India by its people, while an assertive China is considered the third top threat to the country, a latest Pew research survey said today.

In India, 66 per cent of the respondents considered Islamic State of Iraq and Syria (also known as ISIS or ISIL) as a major threat, while 47 per cent said they considered global climate change as the major threat, the report said.

ISIS is named as the top threat in a total of 18 countries surveyed mostly concentrated in Europe, the Middle East, Asia and the US, it said.

Forty-four per cent said China posed a threat to India. This was closely followed by cyber attacks (43 per cent), according to the report.

Chinese and Indian troops are locked in a face-off in the Sikkim sector's Dokalam area, also claimed by India's ally Bhutan, for over a month after Indian troops stopped the Chinese army from building a road in the disputed area.

While China tops the list among three countries in terms of threat perception for which Pew did the survey, it is quite low for the US (19 per cent) and Russia (17 per cent).

In fact, China is increasingly being seen as an emerging threat by many countries in the world, the report said.

In South Korea (83 per cent) and Vietnam (80 per cent), the respondents considered China's power and influence as a threat.

In the US, 41 per cent of the respondents expressed concern over Chinese power and influence. It was also a country of concern by people in Spain (51 per cent), Japan (64 per cent), Philippines (47 per cent), and Ghana (46 per cent).

ISIS is clearly the primary concern among the issues tested in Europe. Many Europeans also see climate change as a major threat to their countries.

In the Asia-Pacific, the ISIS and global warming rise to the top as major concerns, but a median of roughly half (52 per cent) also worry about cyberattacks, Pew said.

A median of 47 per cent across the region says China's power and influence is a major threat, the report said.

China's power and influence are seen as a major threat by a modest median of three-in-ten across Europe, it added.

Pew said across seven Asia-Pacific nations surveyed, a median of 62 per cent see ISIS as a major threat and 61 per cent see global climate change in the same light.

About half across the region see cyberattacks and Chinese power as a major challenge.

Fewer are very concerned about the global economy, refugees or American and Russian power, it added.
