* Gold breaks through $1,310 barrier

* Sterling waits for signals ahead of Brexit votes
* Oil higher after U.S. imposes Venezuela sanctions

NEW YORK, Jan 29 (Reuters) - Gold hit an eight-month high while world stock markets were mixed ahead of further U.S.-Sino trade talks, a raft of technology company results starting with Apple later on Tuesday and an impending Federal Reserve decision on interest rates.
The U.S. dollar was little changed and oil prices rose after Washington slapped sanctions on Venezuela' state-owned oil firm in a bid to curb its crude exports as traders prepared for major events such as a key Brexit vote later in the day.
Investors expect the U.S. Fed to adopt a more cautious stance when policymakers release a statement on Wednesday after a two-day meeting. U.S. economic data that came in softer than expected in December and a sharp downturn in financial markets are expected to keep the Fed from raising rates.
Equity markets in Europe rose as investors bid up stocks considered safer during times of economic uncertainty, such as utilities. However, a gauge of global stock performance edged lower as stocks on Wall Street fell amid a ream of mixed earnings reports and caution due to the U.S.-China trade spat.
MSCI's gauge of stocks across the globe shed 0.04 percent, while the FTSEurofirst 300 index of leading regional shares rose 0.9 percent.
The Dow Jones Industrial Average rose 12.11 points, or 0.05 percent, to 24,540.33. The S&P 500 lost 8.26 points, or 0.31 percent, to 2,635.59 and the Nasdaq Composite dropped 59.69 points, or 0.84 percent, to 7,026.00.
The information glut this week will make it hard for people to come to a conclusion but the trade talks with China, which begin on Wednesday, are the overriding issue for the world economy, said David Kelly, chief global strategist at JPMorgan Funds in New York.
What Washington, and possibly Beijing, fail to understand is that the uncertainty about trade is slowing the global economy, which will show up in East Asian PMI manufacturing data for January to be released on Thursday, Kelly said.
"The biggest tax levy by Washington is an uncertainty tax, and it's the biggest threat to the markets and the economy this year," Kelly said.
Tensions were high after U.S. officials announced criminal charges against China's telecom giant Huawei for violating U.S. sanctions against Iran.
For Asia, the blow was cushioned by promises of more Chinese stimulus but Beijing had berated Washington for blocking tactics in its World Trade Organization appeal against U.S. tariffs.
Amid the uncertainty, safe-haven gold broke through $1,310 an ounce to reach its highest since May last year.
Oil price gains were capped by abundant supply and signs of a slowing Chinese economy. Brent crude oil futures surged 1.94 percent to $61.09 a barrel while U.S. West Texas Intermediate (WTI) crude futures gained 2.44 percent to $53.26.
Market participants will have catalysts for trading all week, with more than one-fifth of companies on the benchmark S&P 500 index reporting results, including Amazon, Microsoft and Facebook.
Apple, which issued a profit warning this month due to weak demand from China, is due to report after the market closes.
U.S. Treasury yields fell across maturities as investors anticipated strong demand for $78 billion of new issues on sale later in the day and on data showing U.S. consumer confidence at its lowest since July 2017.
Benchmark 10-year U.S. Treasury notes rose 6/32 in price to push their yield down to 2.7241 percent.
The dollar index rose 0.07 percent, with the euro down 0.12 percent to $1.1419. The Japanese yen firmed 0.03 percent versus the greenback at 109.32 per dollar.
