Japan’s Nikkei fell on Monday as renewed trade worries hurt sentiment, while Renesas Electronics tumbled on concerns about how it would finance its plan to purchase a U.S. chipmaker.

The Nikkei share average .N225 shed 0.7 percent to 22,707.38.

U.S. President Donald Trump said on Saturday there was no need to keep Canada in the North American Free Trade Agreement and warned Congress not to meddle with the trade negotiations or he would terminate the trilateral trade pact altogether. Fukunaga, chief executive of Investrust, said given the U.S.-Japan trade talks this month, “this news suggests a discouraging outlook for us,” adding that many investors are staying on the sidelines for now.

He said there are concerns that Trump will ask Japan to take specific steps to lower its trade deficit with the United States.
