Chinese appliance maker Midea made a takeover offer Wednesday for German industrial robot maker Kuka, a move that it says would help it capture a larger share of the "future service robots market." Midea said it would offer 115 euros (about 130) a share to buy all the Kuka shares it doesn't already own. The Chinese company, which is based in southern China's Guangdong province, raised its stake in Kuka to 10.2 percent in February. Indirect holdings of Kuka stock bring its current total ownership to 13.5 percent. Chinese companies have been on an overseas acquisition spree as they use their cash hoard to buy up foreign technology to bolster their competitive positions at home.
