China will keep its doors open to global investors while ensuring steady economic growth, Vice-Premier Zhang Gaoli said on Saturday.

Speaking at the opening ceremony of Boao Forum for Asia, Zhang said China will continue to improve the environment for overseas investors and allow them wider access to industries such as service, manufacturing and mining.

China will also encourage overseas companies to list domestically and issue bonds in the domestic market, Zhang said.

"They will be treated equally [as domestic enterprises] in areas such as government procurement and enjoying policies related to the Made in China 2025 strategy," Zhang said.

"We will always keep the door open and open ever wider," the vice-premier said.

While sticking to the opening up process, China wants to step up efforts in ensuring balanced and healthy growth, Zhang said.

The Chinese economy achieved 6.7 percent growth last year, contributing more than 30 percent of global economic growth.

Zhang expected the nation to continue to play a significant role in driving global economic growth.

"China is well capable to achieve the 6.5 percent growth target," Zhang said.
