It is also active in the offshore yuan market in Singapore and China's Taiwan, Gupta said.

DBS has established a strategy with a focus on the wealth management business and the small and medium enterprises.

In the Chinese mainland market, it is focusing on the wealth management and the corporate clients, too.

The bank was first locally incorporated in China in 2007, and it had 29 branches across 10 major cities by the end of 2013. It does not disclose its financial results for the Chinese mainland market, but its combined income from China's mainland and Taiwan grew by 12 percent to S$743 million ($594 million) in 2013.

Gupta said he still saw "massive" opportunities for the bank in China despite the slowdown in the growth numbers.

Given that China is now a nine trillion US dollars economy, a seven percent growth would mean growth of $600 billion.

The macroeconomic slowdown may have a more obvious impact on the performance of the banking giants with a huge market share, but foreign banks like DBS can still find massive opportunities from the new growth, Gupta said.

Gupta said DBS positions itself as an Asian bank given that the Asia Pacific will be the region of growth.

Lim Say Boon, chief investment officer, group wealth management and private banking, said that the US equities valuations are no longer cheap, while the Asian equities offers "growth at a reasonable price."

He said he saw a "rotation" among the different regional markets such as the United States, Europe and Asia Pacific to have their bull market runs.

The near zero interest rate is powerful in supporting the equities market as ample liquidity tends to drive down the benchmark rates like the US Treasury bond yield.

The bank recommends "neutral" for Asian equities in three months, and "overweight" in 12 months, respectively, he said.
