Prominent integrated circuit companies demonstrated their cutting-edge technologies at the fifth China International Import Expo, highlighting China's importance in the global semiconductor industrial chain amid external uncertainties.

The United States' new export controls on advanced chip design software show once again that Washington is misusing political power to maintain its edge in the strategically important sector at the expense of other countries' interests, experts said.

Chinese home appliance manufacturers have accelerated their push into the chip sector, as part of a broader drive to ensure the safety and stability of supply chains and reduce their dependence on foreign chip companies, industry experts said.

The Chinese Semiconductor Industry Association said on Thursday it opposes the US Department of Commerce's latest restrictions on US-based hardware manufacturers selling advanced chips and chip-making equipment to China as they arbitrarily interfere with international trade.

Dutch semiconductor equipment company ASML said it will continuously support the Chinese market with openness and focus, and work together with customers, partners and talents to promote the development of the global semiconductor industry.

Vice-Premier Liu He has called for efforts to mobilize resources nationwide to promote the development of integrated circuits, and offer real national treatment to foreign chip experts, which industry insiders interpret as a signal of a new round of more flexible supportive policies for the semiconductor sector amid curbs from the United States.

The Dutch government's plan to exert new restrictions on exports of semiconductor technology will further disrupt the global chip industry and harm Dutch companies' interests, experts said.

China's efforts to achieve proficiency in world-class chipmaking and ride out related US restrictions have received the attention of both lawmakers and political advisers at this year's two sessions.

The number of senior executives and academicians involved in the semiconductor sector who are also among this year's deputies to the National People's Congress and national political advisers, has increased significantly.

The semiconductor market has spawned a growing rivalry between the world's two largest economies, with the US government striving to curb the technological rise of China.
