How do you view China's role in the world today?

China will continue to be a vital shaper of global prosperity as its remarkable growth matures, diversifies and develops quality and depth.

China is the world's largest consumer of energy and could alone account for one-fourth of the increase in global energy demand out to 2040.

At BP, we think gas is going to play an increasingly powerful role in the transition toward a lower carbon future. China looks to be an important factor in that process. We are seeing a rapid shift away from coal to gas in Chinese power generation. Last year, China's demand for gas grew by more than 15 percent - making up around one-third of the world's total gas demand last year.

China could also be on course to become the second-largest shale gas producer after the US by 2040. The US Energy Information Administration says China sits on top of the largest shale gas reserves in the world. BP is partnering with CNPC to explore shale opportunities in the Sichuan basin.

How do you comment on the meteoric rise of Chinese companies, especially in the past two decades?

Our experience has been that great progress can be achieved by working together with the right partners. We are proud to be seen as a trusted and supportive partner for so many Chinese companies.

That includes activities both within China and also around the world, such as with CNPC in Iraq and Australia; with Sinopec in Angola and Singapore; with China National Offshore Oil Corp in Australia, Indonesia and Argentina; and with China National Aviation Fuel in Singapore.

Could China's experiences and practices be used to solve global problems?

In our sector, discussions about the future always come back to the dual challenge.

The transition to a lower carbon future is already under way, and China is doing impressive work in this area. It seems increasingly likely that China's demand for coal has already peaked. Looking ahead, BP's most recent Energy Outlook suggests changing demand patterns and the shift toward lower carbon fuels could cause China's carbon emissions from energy use to peak in the mid-2020s.

At the same time, China is turning increasingly toward renewable energy and nuclear. They could potentially account for meeting more than 80 percent of the increase in China's energy demand by 2040.

This is great progress. But to meet the rapidly rising demand, we are going to need all types of energy - including oil and gas. To advance the energy transition, we need to make those fuels cleaner and more efficient.

What measures are needed if China wants to deepen reforms?

As a long-term investor in China, BP appreciates the efforts and commitment made by the Chinese government to make it easier for businesses like ours to invest here.

We welcome the Chinese authorities' recent decision to ease restrictions on foreign-owned retail sites in China.

Actions like this will help to ensure we can continue to invest in China, make long-term plans and grow sustainably.

What is the most unforgettable experience you have had in China?

Previously in my career I was the chief executive of Air BP. I attended the inauguration ceremony for a major Chinese airport.

This involved welcoming the passengers off the first airplane to land there. You might have expected this aircraft to be carrying business leaders, politicians or dignitaries.

In fact, it was a group of construction workers who had helped build the airport, who were the honored guests.

It has been an image and lesson that has stayed with me all these years.
