In October, two members of the US House of Representatives Intelligence Committee accused two Chinese telecom equipment companies — Huawei Technologies Co and ZTE Corp — of posing a potential national security threat to the US.
A month earlier, US President Barack Obama issued an executive order for Chinese-controlled Ralls Corp to divest its interest in four wind farm projects, located near a US Navy weapons-testing facility in Oregon.
"Economic and trade relations are the most important parts of the positive push for China-US relations," said Wang.
"The Chinese local governments and the US states show strong willingness, and are highly motivated to enhance economic and trade relations," he said.
In 2012, China-US trade reached $484.7 billion, close to 200 times more than when the two established diplomatic ties.
China's cumulative outbound direct investment in the non-financial sector in the US reached $10 billion by the end of 2012, while cumulative US direct investment in China stood at $70 billion.
Dominic Ng, chairman and chief executive officer of EastWest Bank, said: "The US restrictive measures against Chinese investment is only one side of the issue; the majority of American state governments are more than welcoming to Chinese investment, as they want jobs and economic growth.
"We see golden opportunities in the next decade for China's investment in the US."
Jerry Brown, governor of California, agreed, adding that the US government has its own foreign policy, which has nothing to do with those of state governments.
"We are totally open to China — it's about jobs, and it's about investment," said Brown.
California is the largest state economy in the US by terms of economic size, and the ninth-largest in the world.
It is a big agricultural state, while its iconic Silicon Valley is considered the largest concentration of top technology companies in not only the country, but globally.
"Chinese local governments are willing to develop investment cooperation with California in sectors including infrastructure, energy, agriculture, manufacturing, biological medicine and tourism," added Brown.
In 2012, California's exports to China were worth $14 billion, a 300 percent growth from 2000 and the highest of any US state.
Some US companies have been vociferous in their complaints about doing business in China, highlighting market access and intellectual property rights, in particular.
