China's continued economic growth and efforts to ramp up its economic relations with the US will bring "even bigger benefit" to the US economy and its people, Beijing's top envoy to Washington Cui Tiankai said on Monday.

Two days before Beijing convenes the National Congress of the Chinese Communist Party, Cui said he believed this year's meeting promises to continue to bring about win-win scenarios for China and for its global partners, particularly the United States.

Citing figures and sources from the US-China Business Council and JP Morgan Chase, Cui said in an article posted on cnn.com that China has made headway in its reform and a booming Chinese economy has proven a boon to the US.

The 19th National Congress of the CPC, scheduled to open on Wednesday, is expected to unveil new leadership and set a blueprint for national development for the next five years and beyond.

"We expect that the Party congress will illustrate that China's unrelenting effort in reform and opening up has added further momentum not only to its own development, but also to that of the world economy," Cui wrote.

"By strongly emphasizing our outward-looking vision, this year's congress promises to continue to bring about win-win scenarios for China and for our partners across the world, particularly the United States," he said.

Cui said that as previously shown, the twice-in-a-decade congress can be the beginning of tremendous determination and development.

For example, he said, five years ago, when the 18th Party congress concluded, a plan was introduced by China's current leadership to build a new, open economic system.

Over the past five years, the country has turned those ideas into structural reform, economic growth and tangible institutions.

"China's supply-side reform is actually kicking in,"the ambassador wrote, citing Jing Ulrich, managing director and vice-chairman of Asia Pacific at JPMorgan Chase.

According to a Sept 14 CNBC report, Ulrich said at the Milken Institute's Asia Summit in Singapore, "In the past several years, they have been containing capacity growth, they closed a lot of factories in the steel and aluminum sectors. So now, that reform actually has come to fruition."

China has, especially since the last Party congress, increased contributions to international economic governance, both through strong endorsements of globalization and free trade in the international arena, and through groundbreaking endeavors like the Asian Infrastructure Development Bank to address Asia's infrastructure needs, and the Belt and Road Initiative to increase connectivity on the Eurasian continent, according to Cui.

Citing figures from the US-China Business Council, a private, nonpartisan, nonprofit organization of roughly 200 American companies that do business with China, Cui said 2.6 million US jobs are supported by the China-US bilateral trade relationship.

Cui also quoted a report prepared by Oxford Economics for the council in January, which said that by 2030, US exports to China are expected to increase to more than $520 billion, as China is expected to continue to be one of the world's fastest growing economies.

Cui cautioned, however, the mutual opportunities afforded by a globally engaged China are not always on the mind of the US, citing the recent investigation initiated by the US to intellectual property.

He said the probe"showed the overemphasized trade imbalance between the two countries, the misunderstandings about China's debt, and the treatment of foreign investment based on each other's appeals are all major concerns for the bilateral relationship".

"However, through dialogue, our two countries can address these concerns, which in turn will benefit the global economy," he said.
