After hitting a record high by deals value in 2015, worldwide M&A activity has been hurt this year by falling oil prices, worries about slowing growth in China and the health of the financial sector.

A trio of deals for U.S. companies topped the list of M&A announced this week, including Chinese company Tianjin Tianhai’s $6.3 billion offer for U.S.-based Ingram Micro, bringing year-to-date China outbound M&A targeting the U.S. to $23.3 billion.

China, Ireland and Canada account for 88 percent of cross-border acquirers in the U.S. so far this year.

European M&A activity, which lagged the U.S. in 2015, has hit $92 billion so far this year, up 4 percent compared with a year ago, after state-owned ChemChina announced it would buy Swiss seeds and pesticides group Syngenta (>> Syngenta AG) for $43 billion in February.

Goldman Sachs (>> Goldman Sachs Group Inc) holds the top spot in the global M&A league tables followed by JPMorgan (>> JPMorgan Chase & Co.) and Barclays (>> Barclays PLC).
