Senior U.S. officials and experts say the United States needs to rally allies to pressure China to prevent it from stealing advanced technology through cyber espionage. At the same time, key American lawmakers are questioning the readiness and capacity of the U.S. to counter such threats.

The renewed push comes after U.S. federal prosecutors pressed criminal charges against the world's largest telecommunications company — China's Huawei Technologies — its chief financial officer and several subsidiaries for alleged financial fraud and theft of U.S. intellectual property.

US Intel Chief: Russia, China Biggest Espionage, Cyber Threats Russia and China pose the biggest espionage and cyber attack threats to the United States and are more aligned than they have been in decades, the leader of the U.S. intelligence community told U.S. senators on Tuesday.

Huawei denies the charges. Beijing denies its government and military engage in cyber-espionage, saying the U.S. allegations are fabricated.

"The Huawei incident seems like an action against an individual corporation, but it is actually bigger than this," said Hu Xingdou, a Beijing-based scholar. "This is about one state's technology war against another state, about which one will occupy the technology high ground in the future."

The Trump administration, however, said Washington is deeply concerned about the potential of Beijing using Chinese technology firms to spy on the U.S. and its allies.

"China's pursuit of intellectual property, sensitive research and development plans, and the U.S. person data remains a significant threat to the United States government and the private sector," Director of National Intelligence Dan Coats told lawmakers at a Senate Select Committee on Intelligence hearing on Tuesday.

Other officials, including Assistant Secretary of State for International Security and Non-proliferation Christopher Ford, advocate for a global coalition against Chinese technology-transfer threats.

At another hearing, experts said threats that Huawei poses to supply chains and critical infrastructure are "absolutely real."

"We need defensive measures and we need to invest in our own technologies as well, and we need to be cooperating with allies and partners," said Ely Ratner, who was deputy national security advisor to former Vice President Joe Biden.

"We know that the Huawei leadership has members of the Communist Party within it, and the company has a long and deep relationship with both PLA and the Ministry of State Security in China. And of course is subject to Chinese law and their new National Intelligence law which gives the government the right to use the networks and data as they wish," added Ratner at a Senate Armed Service Committee hearing.

Former Deputy Assistant Secretary of Defense Elbridge Colby warned that China may gain "economic, informational, and blackmail" leverage over other countries through data collected by companies such as Huawei.

"This dissolves or corrodes the resolve in these countries potentially to stand up to Chinese potential coercion," Colby told senators.

"We need to be able to form a network that is sufficient and cohesive to stand up to these Chinese threats," he added.

Bipartisan senators have been pushing for the creation of a White House office to fight China's state-sponsored technology theft and defend critical supply chains.

"China and other nations are currently attempting to achieve technological and economic superiority over the United States through the aggressive use of state-directed or state-supported technology transfers," said Senator Mark Warner (D-VA) and Senator Marco Rubio (R-FL) who introduced a bill to fight China's technology threats earlier this month.

"A national response to combat these threats and ensure our national security has, to date, been hampered by insufficient coordination at the federal level," added Warner and Rubio in a statement.

Under the bill, the Office of Critical Technologies & Security would coordinate with federal and state regulators, the private sector, experts and U.S. allies to ensure that every available tool is being utilized to safeguard the supply chain and protect emerging dual-use technologies.

The case has provoked strong reactions in China, including calls on social media for boycotts of American technology companies such as Apple.

Lew Mon-hung, a Hong Kong-based businessman and analyst, says China should fight back in U.S. courts.

Lew, a former member of the Chinese Political Consultative Conference (China's political advisory legislative body), says that China should trust the U.S.'s rule of law and resort to legal measures to clear Huawei's name.

"When the US government filed these charges, China's government, Huawei, or the Chinese public, should use legal means to solve legal problems," he said. "Since Huawei has abundant financial resources, and since the Chinese government has the largest foreign currency reserve in the world, why don't they just hire the best American lawyers? They can build a strong team of lawyers against this case and fight a legal battle."
