The U.S. government has added several Chinese companies and institutions to the Entity List under the Export Administration Regulations, and imposed targeted economic and trade restrictions on them that, if not waived, will limit their access to U.S.-origin goods and technologies, as well as goods and technologies that contain a significant portion of U.S.-origin goods and technologies. The United States has also in certain circumstances threatened to impose further export control, sanctions, trade embargoes, additional import tariffs and other heightened regulatory requirements on China and China-based companies. These sanctions, additional tariffs and actions have raised concerns that there may be increasing regulatory challenges or enhanced restrictions against China and other China-based technology companies, including us, in a wide range of areas. In addition, a number of other countries and jurisdictions, including China and the European Union, have adopted various export control and economic or trade sanction regimes. We believe the immediate and direct impacts on our business resulting from such actions or restrictions are limited, because currently our sales to the entities on the Entity List or other countries or regions have represented a negligible portion of our results of operations. Nonetheless, given the important role played by such Chinese high-tech companies on the Entity List in the global supply chain or in China for industries including telecommunications, information technology infrastructure, artificial intelligence and IoTs, prolonged restrictions against such companies could cause a material negative impact to all such industries, which may in turn materially and adversely affect our business, financial condition and results of operations. Similarly, we cannot predict whether the countries in which we operate or may operate in the future, could become subject to new or additional restrictions or actions imposed by the United States or other governments. Depending on the likelihood, type, effect and duration of any such restrictions or actions which may be implemented in the future, our research and development activities, financial condition and operations may be adversely affected.
In addition, on January 5, 2021, the U.S. government issued an executive order prohibiting "transactions" with persons that develop or control the certain Chinese "connected software applications", including WPS Office, a product of Kingsoft Office. Depending on the definition of "transactions" to be adopted by the U.S. Secretary of Commerce, this executive order may impact our business relationship with Kingsoft Office.
Similar or more expansive restrictions that may be imposed on our business partners or their suppliers, our shareholders, our affiliates or us by the U.S. or other jurisdictions in the future may materially and adversely affect such business partners or their suppliers, our shareholders, our affiliates, or us, which would in turn affect our business, reputation, or transactions involving our securities.
In addition, each of the agreements between U.S.- and China-based companies can be terminated by either party, as applicable, under certain circumstances if necessary Chinese governmental approvals are revoked or become limited or impaired or if public law or regulatory action by the Chinese or U.S. government expressly prohibits or materially restricts the collaboration contemplated by the agreement. The risk of such an early termination event may have increased during the current environment of economic trade negotiations and tensions between the Chinese and U.S. governments.
U.S. sanctions and trade laws and regulations and the related regulations are complex and likely subject to frequent changes. The interpretation and enforcement of the relevant regulations and the imposition of sanctions and other restrictions involve substantial uncertainties, which may be driven by political and/or other factors that are out of our control or heightened by U.S. national security concerns. Such potential restrictions, as well as any associated inquiries or investigations or any other government actions, may be difficult or costly to comply with and may, among other things, delay or impede the development of our technology, products and solutions, hinder the stability of our supply chain, and may result in negative publicity, require significant management time and attention and subject us to fines, penalties, orders or restrictions that we cease or modify our existing business practices, any of which may have a material and adverse effect on our business, financial condition and results of operations. For instance, media reports on alleged implementation or violation of export control, sanctions, trade embargoes or other laws and rules which could be perceived as inappropriate or controversial, by us, our customers, business partners, investees or other parties not affiliated with or controlled by us, even on matters not involving us, could nevertheless damage our reputation and lead to regulatory investigations, fines and penalties against us. Such fines and penalties may be significant, and if we were publicly named or investigated by any regulator on the basis of suspected or alleged violations of export control, sanctions, trade embargoes or other laws and rules, even in situations where the potential amount or fine involved may be relatively small, our reputation could be significantly harmed. Any of these circumstances may cause the trading prices of our ADSs to decline significantly, and materially reduce the value of your investment in our ADSs.
