US chipmaker Intel has approached Taiwan chip giant TSMC about possible investments or a manufacturing partnership, the Wall Street Journal reports. Intel has attracted recent investment and partnerships from firms such as SoftBank and Nvidia and has reportedly held talks with Apple. The US government also holds about a 10 percent stake in Intel after nearly US$8 billion in investments. The discussions come amid concern in the US about reliance on Taiwan for advanced chips, while Taiwanese worry about capacity shifting offshore.
