In its push for 5G, the U.S. government is cracking down on Chinese companies while trying to speed up the country‘s construction. The merger of T-Mobile and Sprint, two America‘s biggest telecom operators, was approved by the head of America‘s federal communications commission (FCC) on Tuesday, on the condition that they build 5G.

     The Wall Street journal reported Monday that FCC chairman said he would propose approval for the merger of T-Mobile and Sprint to the FCC‘s five-member commission. T-Mobile and Sprint are the third - and fourth-largest U.S. carriers, with a combined market capitalization of about $26.5 billion. A merger would make it the second-largest carrier in the US, overtaking AT&T.

     According to the report, the FCC has set the conditions for the deal: the new company will have to build 5G networks covering 99 percent of the U.S. population in the next six years, including 85 percent of rural Americans in the next three years and 90 percent in six years. It will also spin off Boost Mobile, a mobile-phone service, from the new company. The new company will also freeze existing prices for the next three years. The chairman said the agreement to merge T-Mobile and Sprint was meant to speed up the deployment of 5G networks across the US, "a special opportunity for the US, particularly in the countryside".

    The us government attaches great importance to the strategic significance of developing 5G networks against the backdrop of increasing competition between China and the us in communications technology, CNBC said. Given China‘s rapid development in the field, Trump said publicly in the middle of last month that the us must win the "5G race" by restructuring internal resources and mobilizing forces to accelerate 5G network construction at all costs.

      Bloomberg said the FCC‘s top executives‘ aggressive push to approve the merger of T-Mobile and Sprint reflects a sense of crisis in the U.S. in the sector, particularly in communications equipment, where private companies are struggling with efficiency and quality. But concerns and criticism remain high over the uncertain prospect of a merger. The journal said the merger would require approval from both the FCC and the U.S. department of justice, which is still reviewing the deal and is leaning against it on the grounds that it could increase industry monopolies and affect fair competition. The communications workers association of America also opposes the deal, arguing that it could lead to job losses and job losses
